Both are needed. If I had to pick just one I'd go with Fes. Would love to have Amundson on the squad though.
Who do you want the Jazz to sign with the remainder of their MLE? I would personally go for Amundson. He would be a perfect back up for Paul Millsap at PF. Please no Fesenko. My depth chart:
PG: Deron Williams, Ronnie Price
SG: C.J. Miles, Raja Bell
SF: Andrei Kirilenko, Gordon Hayward
PF: Paul Millsap, Louis Amundson
C: Al Jefferson, Mehmet Okur
We already have a backup for Millsap. His name is Al Jefferson. You start AL at C. He slides over to PF when Paul sits down. Then you bring in a legit center. Fes for now. Or Okur once he's healthy. That's the problem. We have three starting PF's (Millsap, Jefferson, Okur) and only Fes as a legitimate center. We need to get BIGGER. So no Amundson.
Three YEARS from now? Fes needs another three years only if Sloan continues playing him at a rate of 3 to 5 minutes per available game.Right now for an immediate contribution to this coming season I'd pick Amundson but 3 years from now I'd pick Big Fess.
