Moore's probably best-known for preventing the Baltimore Ravens from going to the Super Bowl in 2012, by deflecting a would-be touchdown pass in the dying moments of the game. He was since cut by the New England Patriots, and played the past three years for the Dallas Cowboys, primarily as a slot cornerback. He'll probably compete with Leonard Johnson for playing time at that position. Hopefully, he'll actually win.
Moore, like all other defenders the Bucs have targeted this year, played in a similar system to Lovie Smith's. The transition to a new defense shouldn't be too difficult.
The Buccaneers also re-signed fullback Jorvorskie Lane to a one-year deal, according to Greg Auman, citing Lane's manager. Lane made a pretty solid impression last year, but injuries and a PED-suspension limited him to just nine games. He's a solid blocker who has some potential as a receiver, but won't exactly break any records with the ball in his hands.
