Draft Watch: NFC North

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.

Chicago Bears

The Bears started five different safety combinations last season and have a pressing need for a ball-hawking free safety. Al Afalava could fit as a strong safety, but the Bears don't seem to trust any of their incumbent safeties in deep coverage. The Tampa-2 scheme doesn't always put safeties in position to make big plays, but the Bears' free safety has too often been a liability. Chicago could also use depth at defensive end after the death of Gaines Adams and the expected departure of Adewale Ogunleye.

Detroit Lions

Depth is an issue at most positions, but none moreso than in the Lions' interior offensive and defensive lines. They are in position to draft an elite defensive tackle with their No. 2 overall pick, be it Oklahoma's Gerald McCoy or Nebraska's Ndamukong Suh. They also will be scouring the nation for candidates to play both guard positions alongside center Dominic Raiola. A receiver to steal some coverage from Calvin Johnson should be a priority after the middling performance of free agent acquisition Bryant Johnson last season. There could also be a need at tight end, where starter Brandon Pettigrew is recovering from a torn anterior cruciate ligament and his two backups -- Casey FitzSimmons and Will Heller -- are eligible for unrestricted free agency.

Green Bay Packers

Both of the Packers' starting offensive tackles, Chad Clifton and Mark Tauscher, are pending unrestricted free agents. At 34 and 33, respectively, neither player has a long career ahead of him. The Packers might have addressed one of the positions by drafting T.J. Lang last year, but they could use additional depth and options considering both positions must soon be turned over. Injuries last season revealed a need for depth in the defensive backfield, especially at cornerback, and the Packers also need to determine whether they will replace outside linebacker Aaron Kampman.

Minnesota Vikings

Whether or not quarterback Brett Favre returns in 2010, the Vikings must establish a succession plan at the position. They've drafted three quarterbacks in the past four years, but among that list -- Tarvaris Jackson, Tyler Thigpen and John David Booty -- none are signed for 2010. There's no reason to believe the Vikings consider Sage Rosenfels a long-term solution, so drafting a quarterback would seem to be among their highest priorities. Another area of need is at cornerback, where starter Cedric Griffin is recovering from a torn anterior cruciate ligament and nickel back Benny Sapp is a pending unrestricted free agent.
