He has some decent pop. His power is only unremarkable compared with some of the heavier handed fighters in the division.
He's been a bit of a fooler. I thought in his beginnings that he was more a puncher and then it became evident that it's just not his game. Chagaev was a bit like that. There were some opponents indicating Ibragimov was packing a punch that was significantly harder than expected but it just wasn't his game to fight as a puncher. Parker might be a little like that where his physical ability to show stopping poweriiiiiiiii9bv vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv-okay, that last bit was my cat, but I'm just saying p;;;;;;;;;;;;;;;;;''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''Cat walked back the other way.

He's a no urgency fighter. If he's winning he's not gonna press the issue unless......................
Once he gets past the mid rounds and is tired his power zaps badly and he has to put a lot of energy into generating it which he doesn't tend to do. He'd rather try to edge boxing rounds with lighter punches than waste energy on big punches that fail to return on investment.
Average for the top tier, and as others have pointed out, some of it is because he is a scientific boxer and doesn't set down.
He was never a big puncher compared to his rivals but any heavyweight at that level can end a fight if they land properly all it takes 1 punch
People say this all the time when they see photos, and the boxer in reality is the same on the scales and in the ring. Parker is juiced up and beefed up. Unfortunately for him, that is at odds with stamina. Apparently Fury is a feather-fist but he stopped a good version of Wilder twice, knocking him down about five or six times. Parker couldn't put over the shell of Wilder once in twelve rounds, and Zhang had no problem doing so.
