Ruiz Zhang Wilder Chisora Takam Meehan, Dimentrenko, H. Fury, and Leapai are all respectable to one degree or another.
I'll have to re-watch it again tbh, but on the night, from memory, I defo had Parker nicking it or at worst a draw. But I'll agree that Parker could have done more in the middle rounds. Parker could have a tendency at times, to take time out or simply not assert himself when he could have done in quite a few of his bouts. He's definitely improved on this of late though.
If you take into account the timing of his fights, I am not sure he even has 5 good wins. Zhang and Ruiz certainly count, but, Zhang was 40 and in dreadful shape. It goes without saying that Ruiz is always in terrible shape.
