One thing for sure, Lucifer would feel right at home.
About half of the Ten Commandments have been broken by these fools; ****, Lucifer might think it was a coup taking place.
Through, in the end, I could see things playing out like this:
The UL fan would get it first; they are the best at lasting only 15 seconds, so I can see them going down fast in a fight.
UNC fan get exposed real quick; he would probably act like Judas and deny everything, lying like they do so well at UNC, his *** would be the second to get creamed.
The IU fan might make it for a round or two. Lucifer might get distracted with all that clapping thinking the IU fan was either cheering him on or trying to give him a hand job.
The KU fan will be the last to go I feel. They will probably act like they do all the time, giving Lucifer a little pause thinking God was in there and this would be a real battle for him.
When all the smoke cleared, God would sit back and watch his Cats play some ball.
