Let's say he turns pro around 2012 and reaches his prime around 2016. How does he do vs: Fury Joshua Wilder Chisora Whyte Povetkin Parker Joyce Zhang
About the middle of that list maybe. He had some size and timing and could crack really hard. On the other hand there's some big dudes in there that hit just as hard or harder. His boxing was ok but not better than Povetkin or Fury. He may have beaten Parker early on but JP has improved a lot and I'm not sure he'd beat the levelled up version we have today.
