>>10953241idk but as far as I remember the heat was almost entirely between Punk and the Bucks, Kenny was even seen talking to Punk after the fight. Kenny is obviously going to support his friends, but he doesn't have personal heat with Punk.
In my view the only matches that make sense to main event Wembley, based on the booking, are MJF vs Adam Cole, Punk vs Ricky Starks, or Punk vs Jay White. Outside shot of MJF vs Punk but even if they were inclined in that direction it would probably be saved for All Out in Chicago.
Those all seem like weak main events to me, but they're the matches that the booking is hinting at. If you could get the Punk vs Kenny match, that would blow all those other matches out of the water in terms of importance/significance.
