I have seen him in two scrimmages, spring and a few practices Mayor. I like what I see, but not sure it is a real step-up. His throwing style is about the same as the others on open and short passes. Very different on the long ball. No question he has a good arm, has a very large arc on the ball. Positions the passes well, better than Davis, not as good as Wells or Mays. Seems to have the best (by far) speed on the ground. He truly out-ran a safety and 2 DB's on that TD last weekend. Then again, his plays were primarily running so we get a good look at him.
Let me point out how much I feel all of the QB's have improved Mayor. Could it be the presence of Hosick? Very well could be. Wells is playing as well as he has ever played ...Davis and Mays are playing better than they have ever played. Mays is on headset most all the time.
