But normal was not good enough for Okur to be a convincing center on both ends of the floor most of the time in the past, except as a clutch shooter and a Yao-killer (but defensively only). Above average offensively; NOT above-average defensively.
Now that he's limped into his 30's, he's still no better than a neutral player to occasional help. Utah needs more than that at the 5, and they have one of the deepest rotations and the PF/C spot that they've had in a long time, even without Okur. With all my gripes about Al (especially regarding his effort/skill on (help) defense), I'd usually want him out there at the C spot over an aging Memo, and I definitely don't want Okur playing if it comes at the expense of not playing Kanter 10 to 15 MPG or Favors 20+ minutes per game (at either post position). Let Kanter come in to finish 1st/3rd quarters and start the first quarter, and let Okur toward the end of halves, with a goal of getting a minimum 10 to 15 MPG--just like EK. Whoever does better gets more time.
Like Numberica, I am amazed that you will use a player's prior liability as justification that a mild worsening of that liability is not much of a big deal.
