Foster? As in the 33-year-old, career 7.5 PP30, 10.5 RP30, 0.6 BPG, recently-injured, barely-positive +/- Jeff Foster? Lulz.
At least Gortat logs one or two blocks per 30 (although his +/- was team-worst last season; red flag to me).

Last season, Gortat outproduced Fesenko in rebounds at a significantly higher rate (and somewhat so with blocks), but if you think Fes is offensively limited, wait 'til you deal with 8 PP30 from MG.
At least Gortat brings in that all-important Polish demographic lol . . . .
Don't worry about >$8M per for Harrington; nobody will pay him that. But if he's not signed anywhere, I don't see how Utah can pay more than the MLE without a willing S&T. Not sure why NYK doesn't want him back, although his +/- isn't good, either.

He might be one of these guys who do better in the Jazz system.
I want Foster (tough SOB) over Gortat (slightly more polished ver of Fes) because of the salary commitment due to him (1yr/6.7M vs 4/28M)
