Ten key faces in new places

Why is it that Peyton Manning seems to be a frequent topic of discussion when it comes to the notable offseason transactions?

Last year in this space, Manning's migration to the Mile High City was the top story of the 2011-12 offseason. He signed a five-year, $96 million contract with the Denver Broncos in March 2012, scored the fifth-most fantasy points among quarterbacks, and elevated the production of his top two wide receivers, Demaryius Thomas and Eric Decker, to fifth and seventh in fantasy scoring at the position. That was a substantial improvement upon a 2011 Broncos team that didn't place a single wide receiver in the top 30 at the position in fantasy points.

One year later, Manning's arsenal has only deepened, as his Broncos signed veteran wide receiver Wes Welker to a two-year, $12 million contract in March, again placing Manning front and center as part of the offseason's top story.

Welker's arrival sends ripples through the Broncos' offense. He finished fourth in the NFL with 173 targets last season and has averaged 155 in the past five years, numbers that no single Broncos player has achieved since Brandon Marshall in 2008. Thomas led the team with 142 last season, while Decker had 122 and slot man Brandon Stokley had 57; Broncos tight ends had 145 and running backs 81. And that's for a team that amassed the 10th-most passing attempts (588).

Do the math: Welker cuts deeply into that Broncos receiving pie, and while Manning might be able to keep three receivers productive, someone has to cede targets to Welker. He'll get the 57 vacated by Stokley, so where do the rest come from? The tight ends might be an obvious place, but no team targeted the tight end position fewer than 61 times last season and Manning has a history of involving his tight ends; he hasn't provided his tight ends fewer than 100 targets in a season since 2005. Assuming Welker steals, say, 50 from Joel Dreessen and Jacob Tamme, that's still only 107. There's little doubt that Thomas and/or Decker stand to lose some.

In other words, don't assume any top-five finishes from the receivers, barring some unexpected clarity on who is Manning's go-to guy during the preseason. After all, no wide receiver who was targeted fewer than 120 times finished higher than 15th in fantasy scoring at the position last season. Thomas, Decker and Welker could all reside in the top 20; but there's a chance any might fall short.

At least there's this defense of three-in-the-top-20: The Broncos utilized three-wide-receiver sets 706 times last season, third most in the league. This team is going to throw, and it's going to have all three on the field often.

Welker's arrival in Denver might have been the No. 1 story in terms of player movement this offseason, but which were Nos. 2-10? Read on:

2. Detroit Lions sign RB Reggie Bush

Though one of the more disappointing fantasy players from a career perspective, Bush's stock received a noticeable boost by signing with a pass-happy Lions team, one sure to utilize his receiving skills more than his previous squad, the Miami Dolphins. Having been targeted 107 times per 16 games played with his first team, the New Orleans Saints, Bush's per-16-games target total slumped to 53 in Miami. Now he's with the Matthew Stafford-led Lions, a team that threw to running backs 129 times in 2012 (sixth in the league) and 523 times since Stafford's rookie season of 2009 (fourth). And keep in mind who some of those backs were: Kevin Smith, Jahvid Best and Joique Bell, none of whom is Bush's equal as a receiver. Bush could be due a significant boost in value, particularly in PPR leagues.

3. Atlanta Falcons sign RB Steven Jackson

Perhaps the most prominent free-agent move of the offseason, Jackson's arrival in Atlanta is tempered by the fact that he's now 30 years old, the age at which the majority of running backs in NFL history suffer a steep decline in production. He might be exempt from that time-tested rule -- if used smartly -- as his workload was impeccably maintained in St. Louis: Of the 17 players who had at least 2,000 career carries on the date of their 30th birthday, Jackson is one of only three who never had a 350-carry season during the 16-game era (1978 forward), and he had the third-fewest 25-carry games (21). Plus, Jackson showed no discernable decline in production as a 29-year-old, which might've portended a decline in 2013. The Falcons brought him in to be the pass-catcher and goal-line finisher that Michael Turner wasn't in 2012, and it might be enough to drive Jackson's fantasy point total up -- a rarity for a 30-year-old.

4. New England Patriots sign WR Danny Amendola

Amendola's arrival in New England is actually more of a story because of who he's replacing than his own merits; it's no coincidence that he signed on the day that Welker departed for Denver. Amendola gives the Patriots a receiver 4½ years younger than Welker, and he had a comparable catch rate (68.3 percent, to Welker's 69.4) and lower drop rate (3.1 percent, to Welker's 5.5) the past three years combined working out of the slot in St. Louis. The problem, though, is that he gives the Patriots a far higher risk of absence than Welker; Welker missed only three games in his six years in New England, while Amendola missed 20 combined the past two years. That's particularly troubling to fantasy owners, who are well aware of Patriots coach Bill Belichick's tendency to be tight-lipped on injuries. To illustrate, 20 Patriots were listed as questionable in their regular-season finale last season, so the odds are good that Amendola might spend most of 2013 with a "questionable" listing, causing weekly fantasy lineup headaches.

5. Seattle Seahawks trade for WR Percy Harvin

Fantasy's No. 8 wide receiver just two years ago, Harvin experienced quite a boost at quarterback when the Minnesota Vikings, who have Christian Ponder at the position, traded him to the Seahawks, who have Russell Wilson. Now if Harvin can only stay healthy; he missed three games in his first two NFL seasons (2009-10), and had his 2012 season limited to nine contests due to hamstring and ankle issues. That said, he claims that migraine headaches that once plagued him haven't troubled him in two years, he led the league in yards after the catch per reception (8.52) and didn't commit a single drop in 82 targets in 2012, and he even gets goal-line looks as a running back, boosting his fantasy stock. In Seattle, Harvin might be the biggest boom/bust selection on anyone's draft board -- emphasis on "boom."

6. Arizona Cardinals trade for QB Carson Palmer

Palmer's arrival in the desert finally gives the Cardinals a viable signal-caller, something they haven't been able to claim since Kurt Warner retired following the 2009 season. That's not to say that Palmer is the next coming of Warner; it merely gives the team a fighting chance via the air, critical for the fantasy prospects of one Larry Fitzgerald. Fitzgerald has the best hands in the NFL, with only two drops in 32 games the past two seasons combined, and there was no greater illustration of what plagued him than this: On throws 20 yards or deeper, he had only one reception. Palmer might not have the arm strength he did pre-surgery, but he's an upgrade over Kevin Kolb, Ryan Lindley and John Skelton, and with Bruce Arians at the helm, you can be sure that getting the ball into Fitzgerald's hands will be a priority.

7. New York Jets trade for RB Chris Ivory

Opportunity abounds in New York for Ivory, whose 5.11 yards per carry the past three seasons combined ranks behind only three running backs with at least 250 attempts: Jamaal Charles (5.80), C.J. Spiller (5.38) and Adrian Peterson (5.20). Considering how exclusive that company is, there's only one logical explanation for Ivory ranking multiple tiers behind: His checkered health history. He has appeared in only 24 of 48 games in his career due to a concussion and injuries to his knee, shoulder, hamstring, foot … boy, what hasn't he injured? Ivory should get plenty of work for as long as he's on the field, especially as the Jets transition to their rookie quarterback, Geno Smith. There's a chance at some big-time numbers here, on the borderline of the top 10 at his position. How lucky do you feel?

8. Miami Dolphins sign WR Mike Wallace

Wallace cost the Dolphins a $30 million guarantee, but in his defense, he's a quick fella, having averaged 17.2 yards per reception during his four-year career, fourth best in the league during that span, and eight touchdowns per season. That's a plus for Ryan Tannehill's development. After all, Tannehill had sneaky-good numbers when he threw deep: He completed 44.4 percent of his attempts that traveled at least 20 yards, fifth best in the league, and his 99.0 Total Quarterback Rating on those attempts ranked sixth. Wallace's fantasy production might not suffer at all in Miami, and his presence could grant Tannehill sneaky QB2 upside.

9. St. Louis Rams sign TE Jared Cook

This offseason's transactions seemed to fall like dominoes: Welker signed in Denver; Amendola in New England, replacing Welker; and Cook signed with the Rams, taking over for Amendola as the Rams' slot receiver. A massive target, Cook was nevertheless a disappointment in his four years in Tennessee, scoring only eight touchdowns in 59 games total and averaging 36 catches and 466 receiving yards per 16 games played. Still, he possesses surprising quickness for a player of his size, and his addition signals a distinct shift in team philosophy toward quick, big-play targets. Cook might finally be ready to break out.

10. Minnesota Vikings sign WR Greg Jennings

Harvin's gain is Jennings' loss; the latter decided to sign on as Ponder's No. 1 target. Who can blame a guy for accepting $18 million in guaranteed money, and the chance at a five-year maximum of $47.5 million? But the difference between Jennings' previous quarterback, Aaron Rodgers, and Ponder is stark:

Rodgers: 67.2 completion pct., 7.78 YPA; 27 completions, 11 TDs on throws 20-plus yards
Ponder: 62.1 completion pct., 6.08 YPA; 9 completions, 0 TDs on throws 20-plus yards

Jennings gives the Vikings a much-needed outside receiver, but his fantasy upside is worse in Minnesota than Green Bay, despite the lack of competition for targets. And let's not overlook this fact, lest we dive into overdrafting him: Jennings has appeared in just 21 of 32 scheduled games the past two seasons combined. He's actually more likely to give Ponder a fighting chance of keeping his job than Ponder is to feed Jennings the ball often enough to be a top-shelf fantasy option.

Listed below are some of the offseason's other notable transactions, albeit ones that failed to crack the top 10:
