Speaking of believable threats to The Big Dog, is there any superstar more legitimate than Brock Lesnar? It's no coincidence that the company still has not booked a rematch of WrestleMania 31's main event nor is it a coincidence that the upcoming triple threat main event for FastLane features Dean Ambrose alongside Roman and Brock. The reigning Intercontinental Champion's main purpose to serve will likely be to eat the pinfall as the company looks to keep both Reigns and Lesnar strong heading into WrestleMania. It also keeps the big-money rematch of Reigns/Lesnar II intact as the company heads into their next year's worth of storylines. Lesnar would rank higher on this list if there was a greater chance of this match happening so soon after WrestleMania, but the earliest this match could realistically be expected to take place is at SummerSlam 2016 in Brooklyn. Unless the company decides this rematch is "too big for SummerSlam", then fans may have to wait a whole other year to see this payoff at WrestleMania 33 (which is unlikely). Regardless of when and where, this match will happen, no doubt, as it's one of the top two or three biggest blockbuster matches WWE is currently sitting on.
