You're pretty close Ox...
The reality is that the OL played poorly from a run blocking standpoint...The pass protection wasn't nearly as bad (as say last year). However, while the run-blocking needs improvement for us to progress as an offense, you have to figure that Brown will get better at a) hitting the holes (or the LOS if there is no hole) and not juking and jerking in the backfield...in fact, the coaches must have talked to him, because he was much more effective in the second half...and I'd go as far to say that right now Morris might be a better option than Brown. However, if he doesn't play, he won't get better and no doubt, he will get better...and b) having better knowledge of what options he has once he gets the handoff (which holes might be not be there and which will be there). That is a direct result of his missed time. He is not as fluid as I'm sure he will be behind the OL...
Look for improvement this week...Don't fret...RW will be back soon and then the NFL should beware...
