Quick is looking great, considering. No idea where you got that as a negative. I would sum him up as being handled with kid gloves, no contact, but catching everything that comes his way, good throw or not. He's back making impressive adjustments to the ball he wasn't able to do before last season.
Austin? Austin has been nothing but good. We talked about not liking him on the outside, but that's a size thing mostly. He's made some incredible catches.
My negatives with this tiny sample size would be Davis, Keenum, the centers and Givens.
My positives are much like yours but I would add in Quinn, Cook, Quick, Bailey, and Kendricks.
Foles is also a positive, but he needs to get rid of the ball faster.
