Bedard has a piece up on the QBs:
Newton clearly has more comfort in the system and is playing more loosely.
"He just knows much more about we’re doing. It’s a lot less new learning everyday, more repetition of things he already understands. That would be true for I think every player I have ever coached in their second year in our system. Things slow down. Things make more sense," said McDaniels. "There were things I was telling him to do last year that he didn’t quite understand, but I was telling him, ‘Hey, do it this way. Try and do it that way. Make him the Mike, whatever.’ He was trying to do everything I said. Now, he actually understands the why on most things. That is really the goal for the quarterbacks — when you’re out there trying to read defenses on a play-to-play basis, if you don’t understand why we’re doing something or why you’re supposed to make the protection slide here or there, it’s a tough position to play. The game has slowed down for him. The offense makes a lot of sense. Like I said, there’s a lot less new learning for him.”
He has stretches where you're like, 'Hey, that looked pretty good.' That even happens on his worst practice days. Certainly, the running aspects help him and he looks comfortable.

The bad news for Newton is that Jones appears to be a sponge and is getting better, largely, each day and from rep to rep. The ball comes out much quicker and his decisions are better. If that continues, then Jones could win the job. But Newton is also getting more comfortable. There's a long way to go in this.
