Watching it live I figured the LSU guy didn't know the Wisconsin player had already been down. The way he was running so fast it looked like he was returning the INT. But when I saw the replay, it became clear the Wisconsin player was celebrating holding the ball out in front of himself.
I do agree that Les Myles should have been fired years ago. The SEC hack media has been making excuses for him for years. The fact he can't recruit a top notch QB should be good enough. I mean both Bridgewater and Jackson had offers from LSU. Thankfully, they chose the Cards.
