Two observations:
1) AJ is totally finished at the top level. Not specifically because he failed to stop Franklin, but because Franklin at times made him look very vulnerable, and AJ didn't look comfortable in there at all. If it was Wilder landing some of those straight rights, it would have been night night for AJ.

2) AJ is one of the scummiest people in boxing. Throwing Usyk's belts out the ring and stealing his moment, now trying to fight Franklin's team after the final bell. Really nasty piece of work.

1) Joshua gained 11 pounds after the Usyk fight and he was at his absolute heaviest in his professional career. This partially explains why he looked so slow and heavy, he's never looked like that before. Partially, because 11 lbs is not that much and because against Wladimir Klitschko he was only 5 pounds lighter and he was much faster then. Because Jermaine Franklin is a fairly easy tune-up, I assume his team justifiably decided it was the right opportunity to experiment and start accustoming Joshua to a heavier weight. If the plan is to fight Fury eventually, I totally see why the team wanted Joshua to be heavier and more powerful and increase Joshua's chances to push Fury, make him go backwards and make Fury less able to impose his weight while clinching and tying Joshua up.

2) With all that said, I believe he didn't need to change his coaches this time. Yes, he still lost to Usyk with the new team, but he definitely improved and looked a lot better, he actually gave Usyk some trouble and performed better than I expected him to. This is actually the first time ever Usyk looked genuinely in trouble, even if he was able to eventually survive the onslaught thanks to his insanely good in-ring IQ. The change in coaching team after the first Usyk fight was welcomed and turned out to be a good choice. But he changed his coaching team again, and that means starting again from the scratch, because different coaches have different visions and different training approach. And IMO, this time it was unnecessary. He should've stayed with the team that prepared him for the Usyk rematch, I firmly believe he would've continued improving. The body work he showed against Usyk is the key to slow Fury down, take his stamina, stiffen his head and overall make him less elusive. Very few people - if any - actually got to Fury's body, but when they did, the following head shots became less readable and harder to deflect. Joshua has the size and the technique to do that.

I don't have to be correct though - before the second Usyk fight, I believed Joshua's key to potential victory was to turn it into an ugly and dirty fight, utilize his weight and size on Usyk, clinch and tie Usyk up and lean on him whenever he is at mid-range and after every miss, use your lead hand to grab and control Usyk's head and push him around. I didn't believe he had enough time to improve his technique enough to win the rematch. And yet he actually proved me wrong partially. He didn't win, but the fight was actually very competitive. I had Usyk winning 115-113, which is the tiniest possible victory in a fight with no knockdowns and point deductions. But he definitely shouldn't be changing his coaching team so often, otherwise he won't be improving.

3) Why do boxing fans always have this belief the fighter is finished after one or two bad performances? Nothing about today's performance gave me a hint Joshua is ready to retire. He shouldn't retire. He's still young, he still has a lot of potential and I don't see any signs of decline. Unfortunately, AJ strikes me as someone who's way too concerned with and gives way too much weight to the opinions of people on the internet in general and social media in particular. "I can't throw combinations like Rocky Marciano", and yet there is enough footage to prove wrong anyone who believes that.
