There hasn't been definite word of anyone else cross-training at the spot, but in his post-scrimmage presser Strong metioned Patrick Vahe and Denzel Okafor as guys who have at least some prior experience snapping the ball. You'd hate to lose Vahe's ability to be a hammer on the pull and Okafor would mean thrusting ANOTHER true freshman (albeit a mean and powerful one) into a tough and cerebral position when he's more of a natural G/T.
