Draft Watch: AFC East

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: Schemes and themes.

Buffalo Bills: As if the Bills didn't have enough holes to fill, they've chosen to overhaul their defense. New coach Chan Gailey and defensive coordinator George Edwards are converting a Tampa 2 defense into a 3-4. They're missing the keystone of that scheme, a blocker-absorbing nose tackle. Logic would suggest the Bills draft either a nose tackle or an offensive tackle with the ninth overall pick, but they had the need for a left tackle last year and selected pass-rusher Aaron Maybin with the 11th pick. The 3-4 switch is good news for Maybin because he was invisible as a rookie and projects better as an outside linebacker. Still, the Bills will need to infuse that position with more talent in this transformation.

Miami Dolphins: Because quarterbacks coach David Lee and offensive coordinator Dan Henning were the Wildcat innovators, many look at their draft needs through that prism. They didn't disappoint the prognosticators last year when they reached to draft scat quarterback Pat White in the second round for the purposes of using him in their direct-snap offense. I'd be surprised if the Dolphins drafted for Wildcat purposes again this year. White's selection was a disappointment. He was no threat as a passer, and the coaches couldn't figure out a way to use him. Another theme to watch is how the Dolphins draft linebackers. They didn't like the way their linebackers performed under defensive coordinator Paul Pasqualoni, inside linebackers coach Edwards (now with the Bills) and outside linebackers coach Jim Reid. All three coaches are gone.

New England Patriots: The Patriots have incredible flexibility entering the draft with four selections among the top 53 slots. They can go any direction they choose, but will Bill Belichick keep his picks or barter them? The Patriots have tweaks to make all over the place, particularly on defense. Fortunately for the organization, Belichick has a much better success rate when it comes to identifying defensive players early. Some of the Patriots biggest draft mistakes on Belichick's watch have been on offense. They found a keeper with left guard Logan Mankins, but didn't connect on such prospects as tight ends Daniel Graham and Benjamin Watson and receivers Chad Jackson and Bethel Johnson. Running back Laurence Maroney has been a contentious pick, too.

New York Jets: General manager Mike Tannenbaum said at the NFL scouting combine Friday the organization isn't placing any extra importance on collecting draft picks, but the Jets need to sow young talent onto their roster. Over the past three years, the Jets have traded away most of their draft picks to move up in the order and select players such as cornerback Darrelle Revis, linebacker David Harris, quarterback Mark Sanchez and running back Shonn Greene -- all successes to date. But their ranks have been thinned with only three draft picks last year and 13 since 2007. The Jets have used undrafted free agents and castoffs from other teams to fill out their roster, a philosophy that's difficult to maintain for the long haul. The Jets also are affected by the "final eight" plan that prevents them from signing unrestricted free agents until they lose one. A plump draft class would do the Jets wonders.
