Are you just assuming or did you hear this somewhere?
I don't mind Foley's yearly returns because as people said- He puts people over, has fun matches and usually puts people over.
I read about the McMahon headlining Summerslam on a several news sites, and it's always been known Foley wants to work with McMahon. What I'd like to see is McMahon taking his anger out of losing the Battle of Billionaires match on Lashley, and indirectly, ECW as a whole. Foley, as foreshadowed by his rallying promo to the Originals, takes up the ECW mantle and fights for their honor. That's my pure speculation. But the McMahon wanting to work Summerslam and him wanting to work with Foley, I've read.
