Owner/General Manager Jerry Jones loves big, physical, and nasty offensive linemen. Enter Mike Iupati who fits the bill to a tee. The former Vandal needs refinement in technique, but his natural ability is off the charts for a guard prospect. 59 Burnett 91 Linval Joseph I know 40 times don't mean much for nose tackles, but a 5.09 at 328 pounds is damn impressive. Also, 39 reps shows that Joseph is in good shape. Linval Joseph has declared for the 2010 NFL Draft. Joseph had 60 tackles, 13 TFL and three sacks as a junior.
