The only knock I see on Hali is his size, though I don't see it as too much of a knock, being that he is 6-3 267. As for showing up at the combine at 300 lbs, that would be disastrous. Hali is a natural DE. He played DT initially, and it did not work out. What Tamba may lack in traditional pass rushing skills(which I don't believe he lacks much of) and 40 speed, he makes up in motor, heart, and determination. Also, the Castillo comparison isn't really fair to either player. Castillo is a 6-3 306 DT playing a 3-4 DE. Hali is a 6-3 267 DE who will be playing DE at the next level. If Castillo is in a 4-3 defense, he is a DT. Hali is a DE regardless.
