I actually did answer it but then edited it to a much shorter reply because it does seem that you've made your mind up anyway. But since you insisted...
Calling AJ chinny is way too far(granted it's not as good as Ruiz Jr's chin but who's is?), would you call Wilder chinny since he's been stopped now? I wouldn't but I knew it wasn't as good as it was hyped up to be. Simply by some of the times he's been rocked before. He was knocked out cold in sparring against Wlad, he was rocked by Molina(who AJ handled no problem) as well Ortiz of course, who came close to stopping him before Fury actually did it, even Breazeale rocked him(another guy who didn't trouble AJ) before the Ortiz rematch. Off topic but did you notice the ref trying to buy Wilder as much time as possible, taking a point off Fury, while telling him off etc? That's twice I've seen that tactic in Wilder fights.
Anyone can get hurt or knocked out in boxing but you can't say chinny when the only people who have rocked AJ, do actually have decent power. That's not how it works. You can't say Whyte doesn't have power, you definitely can't say Wlad doesn't have power(or any man with 53KOs on his record) and he caught him with that straight right that has done the job on so many fighters before(it's better than his left hook for me). He got up, may have been on wobbly legs but who wouldn't be? Povetkin is another known puncher who was landing clean on the inside, he felt them but he was never even rocked in that fight. Ruiz Jr does have power and lightning fast hands, but it was the shots behind the head that did the damage in the 3rd and the 7th, the rest was accumulation of heavy shots, it was never one shot that put him down. In fact in the 7th AJ ate a clean shot on the chin in an exchange and it didn't phase him, which IMO was when Ruiz Jr decided to go back to the punch that did the damage in the 3rd. Smart but dirty.
AJ being predictable is also off the mark because he's beaten too many top ranked guys for that to have any credence. You don't beat all those guys, some very accomplished and experienced guys if you're predictable(AJ hasn't been fighting journeymen his whole career like some). He's a student of the sport, the sweet science if you will. Wilder has shown none of that, he fell in love with that right hand power long ago(10+ years), he barely talks about past boxers, doesn't seem to respect the history etc. I suppose he doesn't have to but it shows the mentality. People draw inspiration off past great boxers, if they are constantly looking to improve.
It doesn't get much more predictable than Wilder, he's looking for one punch the whole fight, the jab is merely a range finder or a deterrent at best for him. AJ definitely has shown that willingness to add more to his game all along, which is why the schooling he gave Ruiz Jr was no surprise to me. I still think he will go back and do a 3rd fight to avenge the stoppage but nobody is in a rush to see that yet. Ruiz Jr hasn't shown much encouragement so far unfortunately, of a willingness to redeem himself, for coming in heavy, then using that as an excuse. Especially when he accurately predicted AJ's fight plan: "he will move around the ring more but we have a plan for that" what plan was that then Andy? IMO coming in heavy was all so he had an excuse. I like him but that was poor and so are some of his fight tactics. He has his strengths but footwork and head movement have never been among them.
Wilder always has a punchers chance but he's nowhere near the boxer AJ is. I don't know if anyone noticed the way AJ was throwing the jab in the Ruiz Jr rematch was very similar to the Kronk jab. It was snapping Ruiz Jrs head back much like Fury's was on Wilder. One of his trainers talked about that after the fight. AJ has shown a better defence than Wilder, who thinks leaning back with a weak guard will be enough to get out of the way of a fighter stepping forward at you. AJ did make similar mistakes in the first Ruiz Jr fight but how much of that was about him not being with it from the end of the 3rd round? The footwork wasn't all new to AJ who was GB olympic trained, they work on all of that, he went back to basics and took it up a gear. AJ doesn't have amazing head movement but it's at least better than Wilder's as is his guard. It's rare a fighter adds head movement later on his career but you never know, wouldn't put it past someone like AJ, very dedicated to say the least.
I will leave it at that, this is why I deleted it the first time around because the post was getting too long. I'm actually happy for Fury and don't feel the need to bash him at this point. I don't get the AJ hate personally but that's just me.
