Kolb clearly the most mechanically sound QB on the roster-----no news here-----of this bunch he has always been the most sound with his mechanics.
Too many balls hitting the ground probably speaks to the poor mechanics of our QB's not named Kolb. Meanwhile, many reported that Kolb was too quick to move laterally in the pocket which forced panic throws.
I have not heard from anyone else but Kemp that Floyd has been a disappointment so far. Smoothe route running was never his forte. His strengths have been speed and size, coupled with strength and athleticism to go up after the ball. We will not experience any of that until the pads go on. Meanwhile, if I recall, Haley worked Fitz very hard when he came aboard to both increase his speed and improve his poor route running. Floyd has a long camp and 5 pre-season games in which to improve on those listed weaknesses, meanwhile it is his strengths that caused us to draft him, (just as it was with Fitz). I see no real cause for concern at this juncture. (Now, if he comes back next year and is still a poor route runner, and has problems lining up, the I will be concerned.) I don't expect him to challenge for #1 WR this year, only that he provides a target on the field opposite Fitz that commands defensive attentions. If he does that, we will be well on our way to developing another elite receiver.
