Hot Button: AFC East

Posted by ESPN.com's Tim Graham

The top issues facing each team in the division:

Buffalo Bills

Primary issue: The Bills had the weakest pass rush for an NFL team that wasn't an out-and-out doormat. They recorded 24 sacks all season. Only the Cleveland Browns, Cincinnati Bengals and Kansas City Chiefs had fewer.

A significant problem was the loss of Pro Bowl defensive end Aaron Schobel for all but the first five games because of a foot injury. But he managed only one sack when he was available. The Bills haven't gotten anything out of John McCargo, a defensive tackle they traded up to draft 26th overall three years ago. He has started zero times and has notched 2.5 sacks.

The Bills lost defensive line coach Bill Kollar, who accepted a promotion to be Houston Texans' assistant head coach. Fired Green Bay Packers defensive coordinator Bob Sanders has replaced him.

Solution: If Schobel recovers and Sanders can figure out a way to unlock the lackadaisical McCargo, then the Bills' defensive line might spring back nicely. The Bills hold the 11th overall draft choice, and top-rated pass rushers Brian Orakpo of Texas and Everette Brown of Florida State could be available.

Secondary concern: The Bills need to build some goodwill between themselves and their fans. Given the dreadful economy and the team's recent past, even the most ardent Bills supporter has plenty of reasons not to buy tickets. The Bills haven't made the playoffs in nine years. Fans are down on management's decision to stick with head coach Dick Jauron.

Solution: As much as Bills fans despised former general manager Tom Donahoe, they have to admit he knew how to get them excited with high-profile offseason moves such as the Drew Bledsoe acquisition and the first-round Willis McGahee gamble. Would it kill the Bills to provide a little excitement this spring?

Miami Dolphins

Primary issue: Miami's interior offensive line was a major source of frustration throughout the season.

At first, the Dolphins weren't happy with the depth, routinely circulating street free agents through the roster. Rookie Donald Thomas won the starting right guard job but suffered a season-ending foot injury on opening day. Left guard Justin Smiley, their top offseason free-agent acquisition, played well but went down with a gruesome leg injury in Week 13. The front office has decided center Samson Satele isn't sturdy enough to handle 3-4 nose tackles.

The Dolphins went into 2008 excited about their running-back tandem of Ronnie Brown and Ricky Williams, but their inability to run inside limited offensive options and forced the Dolphins to try the exotic Wildcat offense, which put two tackles on the same side of the line.

Right tackle Vernon Carey is a free agent. If the Dolphins re-sign him, there's talk of switching him to guard.

Solution: The Dolphins are searching for a center to anchor their offensive line. Free agency is an option, but drafting a center such as Alex Mack of California or Max Unger of Oregon creates a tantalizing proposition of a formidable line that can stay together for years. Satele could shift to guard and provide depth. Thomas will be back. No. 1 draft pick Jake Long went to the Pro Bowl.

Secondary concern: As ownership switched from Wayne Huizenga to Stephen Ross, football operations chief Bill Parcells renegotiated his four-year contract to include a permanent walkout clause with full pay. Parcells can leave whenever he desires for any reason he wants.

Solution: Leave him alone, Steve.

New England Patriots

Primary issue: The three biggest concerns for the Patriots this offseason are Tom Brady's ACL, Tom Brady's MCL and Tom Brady's knee infections.

Much of the Patriots' offseason -- and beyond -- hinges on Mr. Everything's status for 2009 because roughly $29 million in salary-cap dollars are tied up between him and his insurance policy, Matt Cassel.

That massive allocation will affect how flexible the Patriots can be when it comes to signing free agents or hammering out extensions to players they want to keep around.

Solution: The Patriots must clear Cassel's one-year, $14.65 million guaranteed contract off the books by trading him, but they might not be able to do so. They need to make sure Brady is healthy enough first, and they might not know for months.

Secondary concern: Brain drain hasn't been a problem for the Patriots yet, but recurring defections could catch up to them eventually. Vice president of player personnel Scott Pioli is the Kansas City Chiefs' general manager. Offensive coordinator Josh McDaniels is the Denver Broncos' head coach. Other respected assistants have shuffled about.

Solution: Head coach Bill Belichick has to maintain his remarkable knack for finding and nurturing football minds who always seem to thrive in the Patriots' already-established culture.

New York Jets
Primary issue: The chief concern evolved a little on Wednesday, shifting from "How long will the Jets have to wait on Brett Favre?" to "How will the Jets replace Brett Favre?"

Management insists it's focusing on the three candidates already on the Jets' roster. But Kellen Clemens has made only eight starts, most of them frightful. Brett Ratliff and Erik Ainge have combined for zero NFL game snaps.

The Jets are downplaying their interest in locating another candidate through free agency or the draft, but banging those drums so soon would be demoralizing to the three hopefuls and possibly short-circuit a budding competition.

Solution: Rookie head coach Rex Ryan is a defensive mastermind, which means this mostly will be Brian Schottenheimer's problem to solve. Ryan said he wants to run an all-weather offense, which emphasizes the run. That should help alleviate pressure on a young quarterback.

Secondary concern: Despite star cornerback Darrelle Revis and impressive safety Kerry Rhodes, the Jets were miserable in defending the pass last season. They ranked 29th in pass defense, allowing 234.5 yards a game. Opponents completed 64.3 percent of their passes and threw for 23 touchdowns.

Solution: The Jets desperately need an effective cornerback to start opposite Revis. Getting sixth-overall draft pick Vernon Gholston playing like the pass rusher they thought he was at Ohio State wouldn't hurt either.
