You don't need the two guys together to have heat for a match to have build. On one hand, you've got this underdog champ, a guy who some thought would be too small to win the big one, who some still think is out of his depth, despite proving the doubters wrong time and time again.
On the other, a guy in search of redemption for his past mistakes, having spent the last year clawing his way back into the company and back to the top of it.
You've got two guys with everything to win and everything to lose. Heat can help, but it's not always necessary. Besides, they've still got 4 weeks to build that up.
