There are a couple things I noticed from the first game that aren't getting a lot of discussion from what I have read.
First and most important, Braxton really seems to have improved not just his pocket presence as a passer, but also as a scrambler. Last year it seemed like all of his big plays were on designed QB runs or read option plays. I remember being frustrated a lot that as soon as the pocket started to collapse he would make poor decisions when scrambling (which way to go). He would often avoid sacks or reduce the loss, but he didn't make many plays out of scrambles like Terrelle Pryor used to on seemingly every 3rd and long. I read a couple quotes from Urban about how Braxton has improved as a scrambler in the fall and I think he definitely had his best game that I can remember scrambling against Buffallo. There were 2 or 3 plays that seemed to be designed passes that were nice runs for him, including his long run in the 4th. I would have like to see him avoid one or two more of the sacks he took, but let's face it Mack is a phenomenal athlete and maybe the most athletic LB we'll see this year.
The other thing I wanted to point out was the kick coverage. Most teams since the rule change have been just kicking the ball in the end zone and getting touchbacks. OSU seems to have perfected the high short kick at least in week one. The first kick was a touchback but after that Buffalo started on the 18, 15, 20, 8, 24, and 15 yard lines after kickoffs. If we can keep doing this I think it could make a huge difference for our defense. Last year I know we used this strategy but it backfired at times. I know it is a small sample size but it could be a big weapon for us.
