2. The running backs showed why Carroll is "really fired up about that group."

In addition to Carson's big touchdown catch, the running backs had a number of big plays. Rookie Rashaad Penny was one of the bright spots for the No. 2 offense, breaking off two long runs, both down the right sidelined, and Mike Davis continued a strong camp with a couple of nice runs.

"Mike's had a really good camp, he has been very effective," Carroll said of Davis. "… Mike has been very elusive, he's been consistent, he has been versatile, catching the football, running routes, blocking, all of that. He's a tough guy and a terrific competitor, so he has done very well."

In particular, Saturday was a reminder of how effective of a weapon a pass-catching running back can be, not just on Carson's big gain, but on a number of receptions by running backs and even fullback Tre Madden.

"It's an exciting part of the game," Carroll said. "Chris showed us that last year, we just didn't get it going in the early part of the season before he got hurt, but really we have no restrictions on the things he can do. That was a terrific play to start things off. Chris has great hands, his route-running is there, he's a real target, which is common for all of our guys. We have great versatility in our running backs, and that really is a great asset for (offensive coordinator Brian Schottenheimer) in putting things together.
