Even when Adams was RB and there was the whole "Trucker 33" or whatever. When push came to shove, against quality defenses, that OL was bad. See games against big time programs and D's below. They never mauled any defense that wasn't MAC level or lower. And rarely if ever did they win or get the tough yards.
2017 Adams
UGA - 9/53yds - L
Mich St. - 9/56yds - W
Miami - 16/40yds - L
USC - 19/191yds - W
Stanford - 20/49yds - L
LSU - 15/44yds - W
Those are 6 big time programs, big time games, with above average to great Defenses (even at those times). Those are terrible rushing numbers other than the USC game. If the OL was dominant why does a back like Adams never crack 60yds and only have one game over 100yds against D's like those? I picked that year because everyone talks about what a great line it was. There were individual stars but the unit wasn't that great.
