Reading through the painfully agonizing comments from the thread regarding the most dreaded play in Buckeye history made me think about lost Championship opportunity.

If we go with the idea that if one game we lost was reversed and we would definitely be National Champions starting with Woody as the HC how many lost opportunities were there for us to add more National Championships to our resume. 

I can think of a few 2007 and 2020. What were the others ?
