The top prospects: USC offensive tackle Matt Kalil is one of the top overall prospects in April's NFL draft and should be one of the top four or five selections. At 6-foot-7, 295 pounds, Kalil is tall, athletic and agile, and he was a dominant player in college in both pass protection and run blocking. His father was an offensive lineman in the USFL and his brother, Ryan, is a center for the Carolina Panthers. Iowa's Riley Reiff and Stanford's Jonathan Martin are two tackles who could get drafted in the first 25 picks, as could Stanford guard David Decastro and Georgia tackle/guard Cordy Glenn. Wisconsin's Peter Konz is a first-round talent and the draft's top center entering the combine. Obviously, there is a lot for all of these prospects to gain in Indy.
