Ohio State 2011 is an odd choice.
It was the greatest comeback in Husker history, but it came against a .500 team that dominated a lifeless Nebraska in the first half, and tanked when they lost their star quarterback in the second half. Ohio State was still a brand name, but the game meant little that year. OSU lost to Purdue a couple weeks later.
And if it was the best win of the Bo Pelini era, Bo Pelini sure wasn't feeling it. That was the game that resulted in Tapegate #1, where Bo went off on the fans and said he wanted out of Nebraska. I really don't miss that douchebag.
