With 2 minutes to go.. I agree.
But, with 30 seconds to go, and no timeout being called, taking a knee would have been the appropriate thing to do. Had OSU called a timeout, Hell yes... step back and throw it to the end zone.... but, they weren't. They'd conceded the game.
It's the same thing Urban Meyer did against Miami. I guess, the case can be made that "the system" forces such class-less pay... because, hey! Look! It worked. People are on here crowing about a "20-point victory".
But, I still think it is exceedingly poor sportsmanship.
Now, if they'd had 6 seconds left and were on the 30 and were running the kicking team out on the field for a last second field goal -- that would be running up the score.
