If we drafted him he'd see the field. A DE/OLB probably wouldn't see the field. A DL will get rotated heavily. A corner would have to beat out Lowery. A first round safety would probably start, but probably he rotates in to get coached up a year (or 2 with 2011).
Grab the best talent because we're looking to build depth. At least a few of our starters are going to retire soon, and having an Iupati would leave us with no reason to panic.
