Cantwell was the backup to Brian Brohm at Louisville. While he didn't impress scouts with his production, remember the talent that was around him. It was Division 1-AA at best. Cantwell is 6'4" 235 and has the talent to be a second or low first-round pick.
He didn't have success his senior year but that was because he was relatively new and was basically a rookie. Cantwell has the arm, size, and leadership qualities that you look for in a QB. He measured with a 10-1/2 hand size which ties only Mark Sanchez a possible No. 1 pick in this year's draft.
Cantwell can learn behind Hill, Huard and Smith and work himself up into playing time this year. By the time he is ready he will have a good young OL, a great RB, and a pair of up and coming WR's in Hill and Morgan.
At the fifth round, he would be an absolute steal in this draft.
