Well, obviously there are many players who could fill a need for the Bucs without being drafted very high.
Everybody is talking right now about what the Bucs are going to do in the first 3 rounds so I'm thinking of how they cash in after that.
As a UCF student and fan, they're the only college team that I know in-depth. And 2 players who could fill a need aren't attending the scouting combine and might be a good selection for later rounds.
Ishmael was a true defensive leader who always seemed to be in the right place at the right time. CB Josh Robinson played the same way last year, and is a serviceable nickel corner for the Vikings. Ishmael might be more of a fit at Safety, but he isn't overly big at the position. He makes tackles, and makes wide outs make mistakes. If he falls to the 3rd day, the Bucs should consider him.

Murray is a beast. He has enough speed to make people miss, enough size to break tackles, and good enough hands to be a reliable target out of the backfield. Martin will most likely be the go-to back on all 3 downs, so Murray could offer a change of pace. At 6'3 225 lbs, its a different animal to deal with than #22. I haven't heard a whole lot of Murray talk, so he could be a great steal. (All C-USA first team, Doak Walker Award Watch List, bowl game mvp's)
