Have him spend the whole summer working with Hakeem Olajuwon. No doubt in my mind that he comes back next year with better moves and a helluva lot more confidence in his offensive game.
Rudy improving his offensive game (handle, post moves, confidence) would catapult him into contention for the #1 center spot in the league.
I'd like him to perfect one move and one counter, like Kevin McHale. McHale had like 2 moves, but he just put mo fros in the spin cycle for years and years.
Remember all the hype when Kobe and LeBron went and worked out with Olajuwon? And then their footwork wasn't that much better? And Dwight Howard did too. And Dwight Howard somehow got worse. Dwight Howard is more suited to impregnating females (which he is pretty pretty pretty good at) and destroying teams (which he is elite at) than scoring in the post (which he sucks at).
As sexy as it sounds for Gobert to work with Hakeem the Dream, what if Hakeem isn't a good teacher?
Also Karl Malone. Great interview, prototypical modern power forward, spectacular Hardee's pitchman, marginal pro wrestler, adequate 18-wheeler trucker, top-notch dozer driver. Maybe not a great teacher.
Rather stick Rudy with a great teacher/coach (which we probably have on staff *cough* Alex Jensen *cough*) than send him to some hall of famer who doesn't know how to break down what they do by instinct.
