What I caught was talk of seeing if the line could protect on the edges during the broadcast. That's all fine and dandy, but when it isn't working, you abort your plan. After watching it a few times, I'd venture a guess Robert had a concussion prior to the play that caused him to leave the game, and nobody picked up on it. The play when he gets plastered by the blitzing LB, it looks like he slammed his head on the turf very hard. Either way, when the line is failing, you don't leave your starting QB in to get hammered in a preseason game to get more reps.
We're truly screwed if Trent is hurt, because Compton got owned on the majority of pass plays. I saw one play where he actually had time to drop back, set and throw..... and that was the batted ball. Litch still gets blown off the ball often, which is nothing new, and then the young right side of the line getting schooled. I know the line is a work in progress, but again, you see it's not working, you change something.
Robert shouldn't have been in that last series.
