I think Rutgers did it in 2012. Just going off memory though.Someone needs to check this but I also think VaTech is the only team to return a blocked extra point against us, and they’ve done it twice. Lost both games. The other being the Brominski throw back game.
moral of the story, we are going to rip their heart out every time the block an extra point against us and return it for a TD. I suggest they stop trying.
