This is a really tough call.
Oklahoma has the #1 Scoring and #1 Total Offense in the country. They have 1 close 3-point loss to a Texas team who is about to be ranked around #10.
Oklahoma also has an ABYSMAL defense ranked #99 in Scoring and #111 in Total Defense. This has led to them having 4 games they BARELY won by margins of 7(in OT), 5, 1, and 3 points. Plus that 1 point loss was because The Mullet at OSU went for 2 instead of going to OT.
Ohio State has the #7 Scoring and #2 Total Offense in the country. They also have the best win by DESTROYING a #4 Michigan team who had a Top 3 Defense going into the game.
Ohio State also has a less than ideal Defense prone to big plays BUT they are still WAY more competent than Oklahoma and are ranked #56 in Scoring Defense and #67 in Total Defense.
The problem though is they have yet again another pretty much unforgivable loss....this time by 29 points!!! to a 6-6 Purdue team??? They also barely beat PSU by 1, Nebraska (4-8) by 5, and Maryland by 1 yet again because a HC went for 2 instead of going to OT.
Both teams have their pluses and merits but they also both have plenty of Warts.
Jmo I think that tOSU is the the better more complete team than Oklahoma right now. They at least TRY to play Defense where Oklahoma looks like circus clowns falling all over themselves.
But IF Oklahoma beats Texas in the Big12CG avenging their only loss I think the CFP Committee will choose them at #4 and leave tOSU out at #5 AGAIN because of the just inexplicable blowout loss to Purdue.
This is going to be one of the most heated debates of the CFP era and especially is tOSU beats Northwestern by 40-50+ points and say Oklahoma escapes with another ugly shootout type win like 55-54.
