As a translation I take it to mean you're saying that they know what Willis is capable of based on his experience last year, and that JP's failures are typical of the "growing pains" you get with a young QB. I think you add to that fact that JP has made it clear that he's angry about his own performance, that he realizes the mistakes he was making, that some of them could have been avoided had he listened to his coaches, leaving Mularkey to add nothing but "you're right JP."
