Ohio State was a dangerous team this year that showed flashes of brilliance and stupidity....that couldn't get over the top to become a complete team in any game. They have demonstrated they could have had the potential to hang with these two, but they never pulled it all together. They haven't been 9 units strong since January 2015.
Clemson is a complete team and Alabama is too except when they play someone who can play on their level. Then they show cracks. Clemson also benefits from having played Alabama 37 times in the last 4 years and has had nearly the same obstacles to overcome each year. Under the current format and paradigm, they are built to dominate the system. But I'm hopeful that Ryan Day is putting together the pieces to become a complete team in the future.
