Well winning a national title would be against one of those teams you mentioned more likely...
I think you are looking into one game way to much....Ohio St run game probably didn't demoralize Oregon any more than dropped passes, missed RZ opportunities, poor tackling, 3rd down conversions, and a JR. HT Winning QB being off.
Going into the 4th they are only down 28-20...besides their first drive they are penalized every possession. Your QB goes 5-13 in the 4th quarter. That has nothing to do with your small athletic DL, making Oregon pass happy is not much different then their usual offense since they were 10th in the country in passing offense.
Another thing is you keep saying small athletic DL
Oregon DL
6-7 290
6-8 290
6-4 310
6-6 270
There is nothing small about this DL anymore than most college teams...
Ohio St DL
6-5 278
6-2 288
6-4 295
6-4 272
In my humble opinion Oregon was off on offense and that is what cost them the game.....scoring 25 less points than you have averaged all year is telling and we see it happen every bowl season.
So my answer to your question....you do not need to have a NFL size defensive line to win title i.e. Ohio St 2014 beating Alabama
Damn, I am in complete agreement with DC!!!! At issue is not the size of the kid, good research there DC, but philosophies. I hold that offense, as we saw with Oregon, will have off days. We have seen it for years, teams that rely totally on offense have a hard time winning when their offense is out of sync.
