Did Vince McMahon really believe that Bart Gunn could beat Butterbean at W.M. 15 because of his success in the Brawl For All? Also, did the fact that Gunn got knocked the fuck out in 35 seconds have to do with him disappearing from the company shortly thereafter?
Yes and yes. The people in charge, who apparently never watched UFC or boxing, were 100% sure that Bart was going to steamroll Butterbean. Power of the wrestling bubble for you.
