Bruce Irvin, Sack specialist
Depending on what the Giants decide to do with Osi, they could possibly use a true speed rusher opposite of JPP. IMO not only the best speed rusher but pass rusher period in the 2012 draft is Bruce Irvin. The guy has 22.5 sacks over the past two seasons including 14 as a junior. He already possess a nice array of moves relying mainly on his speed/quicknees to press the edge which in turn sets up his inside move. Also despite his size, can bull rush the tackle with some success as well.
Athletically he compares favorably to Von Miller:
Height weight arms hands 40 Bench 3cone 20yard shuttle
Miller- 6'3" 246 33 1/2 9 1/4 4.53 21 6.70 4.06
Irvin 6'3" 245 33 3/8 9 5/8 4.50 23 6.70 4.03
Due to his recent arrest, lack of experience in traditional defense, and lack of effectiveness playing the run its entirely possible that he'd be available at 64.If that were to happen I think he would be a must make selection, and one that we as Giant fans would be very excited to have.
