I didn't say he wasn't worth $10mm or whatever, just that I would not pay a role player that kind of doe if I were in the Jazz' position. If you're Portland then you can match Batum's expensive contract because your owner is a mega-billionaire. If you're Utah then you have to spend the money a little wiser.
Portland is a good comparison if you want to build a contender:
Trey <<<< Lilliard
Burks <<<<<<<<<<<<<<<<<<< Matthews
Hayward < Batum
Favors <<< Aldridge
Lopez << Kanter
That team is at $63mm with Aldridge on a cheaper deal than his next will be and Lilliard on a rookie scale. The team is superior in talent at every position. It's also not likely to be a championship contender with a salary structure that's probably going to be somewhere around $75mm in a couple years.
The Jazz cannot afford to pay Hayward like Portland paid Batum. Korver is a more efficient scorer and slightly better defender and cheaper. That's who I would pay if I were the Jazz.
