Trades and free-agent signings change the landscape as teams formulate their draft boards, with some needs being filled via offseason acquisitions and other holes being opened because of player movement.

Taking value over need is a lot easier when a team fills its most glaring weaknesses before draft weekend, while organizations that fail to do so are more likely to reach to fill needs and have it backfire.

How have things played out so far in the NFC East? Here's a look at the moves each team has made and how they could affect draft weekend.

Dallas Cowboys
The Cowboys were wise to franchise DE/OLB Anthony Spencer, who led the team in tackles and finished with 11 sacks last season. Spencer excelled as a 3-4 outside linebacker, but he played defensive end in college and is strong enough to play there in new defensive coordinator Monte Kiffin's 4-3 scheme.
