Maybe he plays fast, but he sure has a slow 40. He only ran a 4.84 at the combine.

If he's that slow, he'll be a liability in coverage. Imagine him trying to keep up with the slew of 4.6 and faster TEs that have proliferated. That's not a good combination, particularly since he's only 6'2". These measurables suggest a specialist/backup, so I think we'll still be looking for a LB in the draft.
