First post, but I thought I'd share some observations I noticed myself:
1) Edwards is definitely as swift and quick as advertised. Sans the first quick pass (which he dropped) and the fumble, he was shifty and nimble in the open field. The running backs as a whole looked solid yesterday. He had a completely different gear than the DBs on his logn TD run. Cobb has the best vision of the bunch, and Roderick was no slouch in the department either. Kirkwood seemed to have gained some of his burst back, although he was a bit too ploddy and jumpy trying to find holes from what could I tell. Roderick hit the holes hard and quickly, which was great to see.
2) As mentioned, the 2nd string DBs looked great. Perhaps it's an indictment on the WRs, but they pressed and tailed great. Granted, some of the balls were underthrown, but the development there was great to see. Standouts would include Myrick and Jones. Props to the staff for the DB development-- the unit really looks like a strength with a lot of depth.
3) Receivers left a lot to be desired. I couldn't pinpoint it to either QB play or not, but the separation wasn't consistently there. Drewski had a nice step on Myrick on a floater near the endzone that Leidner overthrew (which Myrick nicely intecepted). Jones had a step on his man at one point, but dropped the ball as well. Same with Fruechte. Sardinha and Hutton looked pretty crisp on the underneath routes, as did the backs.
4) QBs were hard to tell with the lack of numbers, but I wasn't too displeased with their play. Leidner had an overthrow and a beautifully placed ball on the left hash that was dropped. Streveler looked quick, although his windup throw lacked a bit of zip. Rhoda had I think 1 throw which he completed. I'm not sure whether to chalk it up to rust or not, but there were definitely some miscommunication between the QB and the WR on several occasions.
5) Speaking of which, I know it was against the 2nd string D, but Mckinzy really looked great. I think he has the best pocket presence of the bunch-- he went through progressions and bolted-out only when necessary. Once again, I know it was against the lower-D, but his delivery was quick and just on an absolute line. I would say that he has the most zip out of any of the quarterbacks. The kid carries himself with some swagger-- can't recall the last time I noted that with a QB. I'm really excited to see how he develops.
6) Woz is all of 6' 9". Anyanwu was a beast on the underneath routes-- I think he can be a solid #2 or #3 TE along with Goodger.
Didn't get much of a view of the linemen (I was too focused on the skill-positions) but there were definitely a couple of breakdowns in protection that I noticed. Run blocking looked pretty solid. I specifically noted Hayes and McAvoy (can't remember which of the two) as getting some decent playing time.
That's it for the O. If anyone wants, I can write up something quick about the D too.
