I know what you mean about the back-to-backs. On the other hand, Wilder showed us a side of him he'd never had to show before. The willingness to go on even as he was being beaten to the punch and was in bad condition..... heart.
Tough to say how his mindset is now after the hard reality that he'll never beat a Tyson Fury.
But let's say his mind and heart are still in it. Other than those two knockout losses, Wilder hasn't been subjected to the type of career that leads to "Punch-Drunk City." He also showed he can more than hang with big bangers like Luis Ortiz.
That's what leads me to believe that... IF... he still has his winning mentality... he can still beat most other HW's out there today.
