Welcome and a nice addition. Tough to stick a walk-on into a skill position, but he does have some speed and quickness and is good with the ball in his hands. I liked his film at DB - seems to have quick closing speed and hits like a safety. He's already 5-11, 195 or so, so not a stretch to see him add weight to play safety.
And, people will get sick of hearing this, but guys around this size with this speed are great candidates for coverage LB spots. The role of the ILB spot is shifting quickly and if we stick with a couple of big, thumpers we'll continually get burned downfield, not to mention using their pursuit against them when they aren't quick enough to react to misdirection.
Anyway, thought for another thread around that, but I can see some of these walk ons playing at 225 to 230 as well as the obvious positions for their size/speed right now.
