I like your enthusiasm but I've long since given up on Oklahoma out of conference. At this point I'm almost surprised when they win any games OOC, much less the high profile games.
Most lines in Vegas have Ohio State winning by 3 to 4 points. I don't see OU winning this one, but may give Ohio State some problems through most of the game. But there are always surprises.
I'm rooting for OKlahoma as I do all Big XII in ooc, but OK lost 2 NFL WRs playing (and a 3rd not) + 2 Olineman from 2015 + good LBs and a DT. Not confident in week 3 to beat tOSU even at home.
