Even though he's going to be a massive face for the next year or so, it is reasonable to guess that Lesnar will himself be back as a heel by the time of WrestleMania 33. It is his natural role. Even during his big babyface run a decade ago, he was only actually a good guy for the space of about half a year. Plus, the current buzz around him can't last forever, particularly when his appearances will be so rare. A heel turn will freshen him up ahead of the final year on his deal. There's also so many great babyfaces who are maturing right now. Sami Zayn, Dean Ambrose, Neville, these are all people who would be suited to a match against heel Lesnar.
