Draft Watch: NFC West

Each Wednesday leading up to the NFL draft (April 22-24), the ESPN.com blog network will take a division-by-division look at key aspects of the draft. Today’s topic: biggest team needs.

Arizona Cardinals

The Cardinals need to get younger in their defensive front seven while improving their outside pass rush. Bryan Robinson is still the most dependable nose tackle on the team. He turns 36 in June. At outside linebacker, 34-year-old Bertrand Berry is retiring and Chike Okeafor turns 34 shortly after becoming an unrestricted free agent next month. It's a tough situation for a team that could lose linebacker Karlos Dansby, 28 and in his prime, to free agency.

Arizona had the right idea when drafting outside linebacker Cody Brown in the second round last year. Brown spent his rookie season on injured reserve. The Cardinals need to get him on the field. They need to develop young linebacker Will Davis, who has shown promise. They need to supplement their front seven in the 2010 draft.

On offense, Kurt Warner's retirement reduces the margin for error. The Cardinals do not need to draft a quarterback early this year, but they do need to continue upgrading their offensive line. Drafting a tackle could make sense. Tight end was a need in the past, but the Cardinals seemed to get through that position OK once Ben Patrick returned from suspension last season.

San Francisco 49ers

The 49ers need to find a long-term starting right tackle, preferably in the draft. They're set at left tackle and center. Both guards showed improvement late last season. Right tackle has been a question mark for too long. Time to find the answer.

The quarterback issue lurks in the background because San Francisco still cannot count on Alex Smith. With two first-round choices, the 49ers could justify selecting a developmental quarterback early while still addressing a short-term need such as tackle. It's not a must, but it should be a consideration if any of the college quarterbacks appeals.

San Francisco is strong on defense, but every team needs pass-rush help and the 49ers are no different. They had 44 sacks, an impressive total, but 24 came against the Rams (two games), at Seattle and home against Jacksonville. And while it's natural for teams to rack up sack numbers against inferior opponents, the 49ers gain nothing from pretending they were a consistently great pass-rush team. Drafting an outside linebacker with a nose for the quarterback surely wouldn't offend defensive coordinator Greg Manusky.

The 49ers also could use an inside linebacker to pair with Patrick Willis, a strong safety to replace Michael Lewis and a cornerback to pair with Shawntae Spencer as the team transitions away from Nate Clements in the coming years.

Seattle Seahawks

Linebacker stands as one of the few offensive or defensive positions Seattle doesn't need to address in the draft, and even that position isn't as strong as it appears on paper. Leroy Hill, Aaron Curry and Lofa Tatupu made it through part of one game last season. They were never on the field at the same time after an opening-week victory over the Rams.

The Seahawks need to upgrade their offensive line to give Matt Hasselbeck -- or any quarterback -- a chance to function more consistently. They need a big-play threat at running back and receiver. They need to identify and acquire Hasselbeck's eventual successor. They need to get bigger at cornerback. They could use an outside pass-rusher to give them what Patrick Kerney gave them before injuries derailed him.

Seattle had zero sacks in five of 16 games last season. The offense's inability to score points created fewer situations ripe for effective pass-rushing, and the Seahawks could help their pass rush with additional scheming. It's also possible the new coaching staff will get more from Lawrence Jackson and Darryl Tapp. I just don't see how the Seahawks can count on these things. They need more raw pass-rushing talent.

St. Louis Rams

Coach Steve Spagnuolo recently reiterated his belief in building a team from the inside out, starting with the lines. The Rams can be good enough up front on offense when their line is healthy. They need more young talent on their defensive line to help Chris Long. They need to build around James Laurinaitis at linebacker. They could use another cornerback, too.

But anyone who watched the Rams last season realizes this team is going nowhere without an impact player at receiver and a quarterback the team -- and city -- can get excited about. Marc Bulger can be OK, but the sense here is that he's finished in St. Louis and the Rams need to find a stronger leader to rally around.

The Rams' draft position and long list of needs makes it tough to draft a quarterback early when there doesn't appear to be an elite prospect at the position in this draft. For that reason, the Rams might be wise to acquire a veteran such as Michael Vick or Chad Pennington to get them through the season while they continue to bolster the roster elsewhere.

The draft board might dictate selecting a defensive lineman first overall, and that's OK. But this team badly needs a playmaking receiver to give the offense punch beyond Steven Jackson. The Rams were unable to address that need in the 2009 draft, but they need to find a way this time.

It's a bonus if the Rams also come out of this draft with a change-of-pace back and an all-around tight end.
