I agree, I liked the way Brown was finishing off his runs and gaining extra YAC. I'm slightly worried about the O-line though, but I think his lack of yardage has more to do with the playcalling and/or Pitt's defensive plan.
I think Pitt went in with the idea that CPep would have to beat them through the air, so they were stacking the box and blitzing a bunch to force him to throw. That being said, I don't think Miami opened up the offense early enough with deep throws to make the Pitt D give them some respect. And then when they finally did start throwing to Chambers more in the 4th quarter, they didn't go back to Brown when he probably would've had a little more room to work with.
Other than the 2nd TD in the 2nd half, Ronnie barely got the ball. With a lead with around 10 minutes left to play in the 4th, they abandoned the run which is just stupid. So I was impressed by Ronnie with what he was given and I think there was enough shown on his part for a positive outlook for the rest of the season. I think he's going to be huge barring injuries.
