If the Bucs want to move back from the seventh overall pick but don't want to drop down too far, the Detroit Lions could be a possible match at No. 10 overall.
Detroit has needs to address in the secondary, but the Lions probably wouldn't need to move up for a safety like Alabama's Ha Ha Clinton-Dix or a corner like Oklahoma State's Justin Gilbert. They could, however, be targeting another weapon in the passing game to join Calvin Johnson and the newly acquired Golden Tate. If that's the direction they want to go in, Texas A&M WR Mike Evans would likely be their target.
A dark-horse candidate for the Lions in a trade-up could be Pittsburgh DT Aaron Donald. Detroit might not be able to afford extensions for both Ndamukong Suh and Nick Fairley, so they might look at Donald as a younger, cheaper alternative to retaining either of those players, especially if they're able to get some value in trading one of them.
If the Bucs end up at No. 10 overall, their best bet could end up being North Carolina TE Eric Ebron, if he's still on the board. While the bigger need for Tampa Bay is at receiver, Ebron is the kind of athlete who will create mismatches for opposing defenses and could be just as effective as any receiver they could draft at that point.
Per the trade value chart, the Bucs could command either a second-round pick or Detroit's picks in both the third and fourth rounds.
