I have been around for a lot of Ohio State football games and have seen some good comebacks. For example, Greg Frye led an amazing comeback against Minnesota, but let's face it that was Minnesota.

In my thinking, there are 2 candidates for the GOAT comeback: yesterday against PSU and 2005 on the road against UM. Troy Smith cemented himself as the slayer of UM in that miraculous 4th quarter 12 years ago (in which I commented to my new neighbor afterwards about what a great game it was not realizing he was a UM grad). 

Which if the two is the best? I can't make up my mind, but I am leaning towards Troy and 2005.
