Jean Sifrin is 27 and hoping to be the sleeper pick of this year's NFL draft. He ran an unimpressive 4.84 40-yard dash at this year's NFL combine and needs to impress scouts in his pro day if he's going to have any chance of getting drafted.
At 23, he was scouted playing flag football, and three years later found his way onto the University of Massachusetts roster. In his only D-I football season the massive tight end caught 42 balls for 642 yards and six touchdowns. He's now on the fringe of being drafted to the NFL, but his age and speed are holding him back.
