Our guys caught on to the moves he does best, so he has to work his repertoire. However, he should be able to shine in the preseason, like he did in the first game, because teams aren't studying his moves.
What stood out to me the most in the Oakland game was a very nice spin move he used on the right tackle, a great hand fake and shoulder dip that left the left tackle reaching for the contact that never came and a nice little double-team split where he used one hand to fend off the tackle and the other to fight off a back (I believe). All of those allowed him to get good pressure on the QB and force him either to scramble or rush his throws.
He also showed good pursuit skills.
