I know sporting news had him #1 but I think that it will be hard for him to overcome the hype of Tebow/Mc Coy/Bradford. It will all depend on the draft order and team needs. Definitely top 5 if he stays healthy and potentially #1 if a team is in desperate need of a defensive stud!
Tebow will not go in the top ten by any means as teams will draft to positional needs and NFL execs still can't figure out what he'll play.
McCoy won't be in there because teams will question his size and other bs nit-picking issues. Bradford,
McCoy, and possibly Dez Bryant would be about the only players from the Big XII that could be picked over Suh at this point in my eyes.
