#1 Matt Riddle vs Brock Lesnar

For years now, even pre-dating his WWE days, Matt Riddle has been talking about retiring Brock Lesnar, and now that The Beast is seemingly back in WWE for the near future, it could happen.
Given the way he's been booked so far in his NXT career, Riddle looks like a dangerous star, and if he is used properly on the main roster, he'll be a main event talent from the get-go.

The Original Bro is quite likable, but beyond that, he's a dangerous striker and one of the most well-rounded performers in the company, and he's only getting better.
If Brock is with WWE by the time WrestleMania 36 rolls around, WWE would be incredibly wise to push Riddle, and if he was the one to retire The Beast, he'd be a mega-star on the level we haven't seen for years with the company.
