QB, and a receiver or two that just started in the system (Trinnamen).
You are right to be skeptical of the claims of our current roster until they show it on the field, but anecdotally there is plenty of reason for Cougar optimism. It's always funny to me when people say "but he only caught x last year" as if people do not have the ability to improve going into the next year. Or, when people say "but they lost y amount of offense when abc graduated" as if there is no one on the roster to replace them.
