Agree. Sloter looked damn good. I REALLY liked how he kept his eyes down field... ESPECIALLY on the play where he continued drifting towards the sideline, & it was over SIX seconds after the snap, when he released the 24 yarder to Raymond. And the best throw and catch of the entire GAME was his connection w/Marlon Brown. 
BUT, it was only his 3rd or 4th throw of the game that went directly into Prosinski(the Bears backup safety)'s, hands. And the play was AWESOME, but he SHOULD'VE hit McKenzie on the 47 yard TD.
I thought Joseph should've shown more flexibility, & when the Bears went up by 7 w/10 minutes left, he should've sent Paxton back out. 
I get that "iron sharpens iron", but ESPECIALLY w/for a QB who's trying to get his feet under him, get into a rhythm, & ALREADY struggles w/the mental side of the game, I think that having Von in his lap 1.5 seconds after every snap, and Harris or Talib undercutting every throw he hurries up, isn't helping his confidence & development.
