The numbers mean nothing at this point. His play on the field means everything. Wether he is playing against 1st or 2nd string D's is not really important either. He is getting time on the field, honing his ability to make a read and with every down is gaining the trust and respect of his team mates. That is whats important. Numbers do not lead a team, people do.
Like it or not (I happen to like it) JP is our starter for now and IMHO he is doing all the right things both on and off the field. If you keep your expectations at a reasonable level he will meet them or even exceed them.
