Special Teams and clock management (which go hand in hand). Team can't afford to fall asleep in "punt safe" situations and give up big first downs on a fake during an obvious fake situation. Had a critical punt block whiff and penalty to prolong a drive in the playoffs also. Play was made going balls out, so it's understandable, but the margin of victory gets tight against good clubs. Need to be able to trust a punter to flip the field. Most importantly IMO need to be able to trust that Shipley can get you three reliably from 48 or so in. Sark gets to call third down differently when he's calling it to get past the chains, rather than to get into 4th and makeable. Shipley's made a ton of kicks, but never in an environment like Columbus.
You guys pointed out the obvious concerns re: time under tension for the OL and even Arch. For whatever reason, I just believe they'll be good enough this year. But this defense... This defense is set up to wreck shit and I'm really excited to see it. I try to be objective and not a prisoner of the moment, but this group should be markedly better than last year. If so, it'll be one of the great units in this era of CFB. In short, all the hype is justified for the team as a whole. National Championship level team. I want to call in every favor just to watch them work at practice - this camp will be legendary if they're wired correctly (which everyone says they are).
