I went and CJ looked good arm strength and accuracy but that is all you could tell with red jerseys on. Weigers has work to do on footwork, receiving the snap, but he has a strong arm and pretty accurate.
Ike Boettger got beat some by Myers/Meirs. Leshun Daniels looks faster, wadley ran well but had a fumble, Derrick Mitchell IIRC looked very good at RB. I didnt watch Boone Myer as much at left tackle but that means maybe he didnt blow a lot of blocks.
I am not sure much could be garnered at this practice about the defense.
I am optimistic that if CJ will do well and if he has a running game the offense will be OK.
I agree that the receivers arent getting a lot of separation but there was one other young receiver that looked to have good speed.
