Towards the latter half of Hibbert's stint in Indiana, Bird and the Pacers brass simply wanted to turn Hibbert into a completely different player... Something that made no sense in terms of his body, physique, and clear potential as a defensive anchor. Bird clearly wanted to quicken the pace of the Pacers team, expecting Hibbert to become a stretch 5 of sorts, it just wasn't feasible and made no sense.
In turn, Hibbert's numbers clearly suffered and I think he had a hard time finding his niche and identity on that squad. Is he Tyson Chandler? No... However, he has the tools, passion for the game, and mindset that could easily place him in the same category. The running joke of the offseaso was "SLLLLLLLLOOOOOOOWWWWWWWWWWW ROY", but that's clearly no longer the case.
I'm not trying to say Hibbert should become Tyson Chandler. I'm saying he should stick to what he does well and forget about being something he isn't.
He should focus all his energy on defense. Accept that Russ, Clarkson, Lou, Kobe and Randle should be the ones scoring the ball. He should forget post-ups when he doesn't have established deep position. Focus on pick and ROLL, rather than pick and pop. Get his ass back on defense, rather than go for the offensive boards (unless he's right at the rim). That sort of stuff.
