When he gets some glutes? Wasn't he saying that he's hip thrusting 200+ for reps? Doesn't sound like lack of glute development to me.
The problem with using an exercise to gauge power. He can't jump more than 30'' and he is incredibly slow. Watch his dunk videos and you see a guy who has undeveloped glutes that don't fire. Hip thrusts are a good glute activator but they use a small range of motion and the load doesn't necessarily equate to power very well. I can get a good workout hip thrusting 225lbs or 505lbs - I have never "maxed" my hip thrust and don't need to. One of the biggest evaluation mistakes you can make (and usually it's self evaluation where we make it) is when we assume that an athlete can do "X" so therefore that part of the body is clearly not the problem. It usually comes from an athlete doing an isolation exercise of limited range of motion and assuming that means that muscle is not an issue. Classic example is a slow sprinter with weak hamstrings who can do something silly like a "Natural GHR" assuming that "I don't have weak hamstrings so that can't be the issue" but not realizing that using your hamstrings as a knee flexor with your knees on the floor doesn't have much to do with hamstring power or development in hip extension during a sprint. Watch an athlete move dynamically an locate where he has weakness rather than referring to a gym lift as evidence of anything.
I agree with that. But you can't say he "has no glutes". You can say he isn't using the glutes that he already has at a pretty good level in terms of strength (yes, isolated movement strength, gym work strength, whatever) well in dynamic movements. That I can agree with. On the other hand, he doesn't seem too fast in ANY movement so I'm not sure it's the glutes' fault - it's either his desire to be fast (he is just "sleepy", "lazy" when he plays or whatever), or his CNS is slow.
We can test that if he agrees to film some "glute unrelated movements" dynamically (can't come up with an idea now) or that keyboard type test (where you press the spacebar as fast as you can for 10 seconds and see what kind of numbers you come with to test "quickness" or CNS speed). I know, silly tests, but they might provide some information (relevant or not).
Back to the glutes idea, I would do dynamic glute movements if I were maxent - KB swings (a ton of them, focusing on the "hip snap"), med ball tosses (focusing on the hip snap), double leg bounds, depth jumps for length etc. I know a lot of these things have a horizontal component in them in terms of hip action - if anybody has any idea about a vertical hip dynamic movement... I'm all ears. Maybe SVJs to rim with little knee travel and a lot of hip bend/hinge (like what Toddday was trying to do in his depth jumps videos).
Plus sprints. If I were as slow as maxent, I would say "fuck this, I will do sprints like crazy" and try different distances and give 110% effort on them. Not only are they great plyometric exercises but also train the hip hyperextension, the posterior chain dynamically, the calves dynamically, stiffen the Achilles etc, all the good stuff.
Obviously, all these besides playing actual aggressive ball (especially on defense, since you don't have the ball and can move freely, you can be quicker/faster defensively and you'll benefit from that type of multi-directional "plyo work").
These are what I feel are the most sensible things for maxent at this moment.
