Fans have seen flashes of Harper's skills in the past year, and there's a lot to like about him. His matches against John Cena recently showed that he can hang with the big dogs, and he is still expanding his moveset such as the superkick he hit at 'Mania. If WWE is looking for an agile big man to take that mantle away from the Undertaker (at least, the younger version of the Deadman), then he could be one to watch. Admittedly, this hypothetical matchup would have required Father Time to hold off for a couple years to establish Harper, but he certainly could have been a guy to take Taker to the limit at WrestleMania.
