Jones had no problem handling the blitz all night. They just finally gave up on the blitz because he was so effective against it. By the time they gave up on the blitz, he had only missed two throws in about a dozen passes against the blitz (one being the INT),
Sure, Jones still has a lot of stuff to work on like most rookie QBs would. But I think he is far, far ahead of most rookies in terms of pocket presence and decision making.
And as for Brady he has a tendency to get rattled when he is hit a lot. It doesn't happen every game he is hit a lot, but it is the best way to make him average or worse. So far I haven't seen Jones get rattled yet.
