IF AJ laid into him the way Ortiz did, don't see Wilder surviving. Ortiz being out on his feet let Wilder win that fight.
EDIT:
The problem AJ has now is he can only fight who is out there. Parker from the fights I've seen of him is nowhere near lop level; average at best. Wilder? Pah. Ortiz? If he's only 38 I'm a Martian.
The big money fight for AJ would be Tyson Fury - storyline being Fury didn't lose title in the ring. Other than that who else is out there? Bellew? Behave...
I suspect history will show AJ in a bad light given the standard of the heavyweight division at the moment.
