He's allowed to be mad about it, I get why he would be. I don't really get why done are insistent he shouldn't be. I also thought he'd gotten a lot better the last couple years so care a little more about it myself, but tbh I completely get him being bumped for Pat myself so I don't even think WWE is "in the wrong" he's just allowed to be upset about it.
I still would have done 3 man on SmackDown with him tho, then he could still do Speed too. Seemed the most logical thing but I guess HHH really doesn't like them
