A known concern with trading either Millsap or Jefferson is the risk of playing a team's bigs three deep.
The Lakers have shown that a three-pronged punch like Gasol, Bynum and Odom can be successful but likewise have shown the consequence of such a system if one big misses games to injury.
Gasol and Odom had to pick up the slack and fatigued themselves early in the season, as well as their bench suffering because of it.
The Jazz have had a similar problem in the past when Fesenko has had to log heavy minutes because of Jazz injuries.
A healthy Okur can loosen up the Jazz's rotations and keep everyone rested even if (God forbid) a player goes down to injury. Many may be concerned because of Okur's injury problems the last two seasons, but I would wager that those are a thing of the past.
The surgery on Okur's Achilles is one that should not have lasting effects, but he was played too early into his recovery for it to have time to heal, resulting in his secondary injuries shortly afterward.
History would also show that Okur is the opposite of injury prone, having played in 70 games or more in eight straight seasons, including 233 consecutively.
I wouldn't be surprised to see Okur suit up for every game this season, once again becoming a stalwart on the Jazz frontcourt. And this season he shouldn't be overworked, minimizing risk of re-injury.
