what I saw:
Great fight
Klitschko was great. A much smarter fight than against Fury. I thought he was going to win by the end of the 8th round(i mean he looked the better fighter and if it was going 12 he'd have out pointed AJ). He should now retire and be happy he went out on his shield. No rematch. Great career where he was starved of quality opposition but he should be remembered as a great. Its not his fault noone was around until the end of his career.
AJ probably surprised everyone with a "late" KO. It surprised me. If it didn't happen early I expect him to gas and then the result would be a close decision. But he got that second wind and did the business. He's legit now and well done to him. He's a likeable guy, mostly respectful of his opponents in the lead up and speaks well. 5 minutes of jawing from Wilder or Fury and I'm almost ready to give up on the sport of boxing. But AJ comes across as a thinker.
Where does this leave Parker? Honestly, hopefully well out of the picture. He's not up to that. It'll be like when Cameron fought Tua. I think Parker needs at least 5kg more muscle across the chest and arms or he'll be bullied. I think he needs a new trainer or at least they need to bring in a defensive specialist to assist Barry. Ideally though i'd just get a new trainer altogether. There has been no progression with Parkers defense or his stamina and its unacceptable to have had a fighter that long and not have made any progress. Parker is especially susceptible to overhand and hooks. Effectively KO punches. The one bright spot for parker is AJs chin. If Klitschko was a power hitter it may have been his had raised. If someone like Wilder, Ortiz and even parker tags AJ I doubt he'd get back up. Getting past those massive arms is the only problem.
I don't want to throw shade on the result or defame AJ but it would not surprise me if he is on roids.
