Right, he's fine when he doesn't have to give ground. But when pressure comes up the middle and he's forced to give 5-6 yards to get outside the pocket, that's when he makes huge mistakes.
Yeah, that was more of what I meant. Brock moving laterally or forward to avoid pressure makes better decisions than when retreating from the line of scrimmage.
Now that he's healthy, I like the RPOs a lot. They seem to settle him down. Plus, the defenders have to play very disciplined, or they will end up seeing number 28 or number 15 celebrating a TD on the Jumbotron
