Parker has the attributes, but he just doesn't have the aggression to effectively use his tools. If he can start roughing up his opponents and throwing a lot more good, hard, fast shots - then JP is a monster.
Are you aware he lost already twice and arguably lost to Ruiz, Takam and Hughie as well? He has some tools to be a good fighter, but he lacks the heart of a warrior. You can't teach him that.
The thing he has lacked is age and experience. He is only 27. He has been a greenhorn in this game. But now coming into his prime
But thats the thing, everything about him is average. And thats the good part. He is good and world class at everything. From physical attributes to skills. Others tend to have their big flaws and overwhelming strengths.
Usyk will clown them all. Parker will get schooled as mr wilder and a close win against fury. Ruiz will get embarrassed and joshua will also get schooled
He's the most athletic guy at heavy, with the most natural physical talent. But something isn't quite there in his mindset, a certain grittiness or will to win at all costs that fighters like Whyte and Wilder possess. He's also not got the greatest boxing iq and tends to make the same mistakes fight after fight, which can make him predictable for anyone that can cope with his speed and hit hard enough to deter him. He's young but he's peaked IMO.
