Well that's what I mean. The match itself would be good I'm sure. But the build up could be bad because Seth isn't that great on the mic. Not a huge issue because the rock could easily carry most of the build up while Seth carries the actual match.
Punk has also done amazing verbal battled with the rock. I could even see bray Wyatt having great promos with him too
He can cut a promo, he doesn't need to be as good as The Rock because nobody is. They will have pretty good promos together and an outstanding match.
