That deals with a lot of assumptions, though. I'm really only interested in Biyombo and Kanter as overseas bigs, and Biyombo just sued his former team and tore up their contract to come into the NBA. Kanter didn't go back to Europe because the only offers he was getting were multiple year deals trying to lock him up and his dream has always been the NBA. European teams aren't stupid, if they're going to invest in a player and they have a legitimate NBA career ahead of them, they try to lock them up (Tiaggo Splitter, Manu Ginobili). Long story short, there's no guarantee these guys can find a team that will just sign them to one-year deals.
And to your first point, guaranteeing disaster? Playing Al Jefferson pretty much takes care of that. I get the feeling Kanter's the real deal, but even if he takes a couple years to become a productive starter, at least he can pass and is still malleable.
I think we'd all like the Jazz to be a playoff team next year, but it's not likely and frankly success so soon might hamper the teams ability to rebuild the team into a real contender in 3-5 years. Striving for/accepting loss is a slippery slope, but I don't think it's unreasonable for the general turnover that has happened to the franchise in the last 2.5 years (Larry dying, half the roster walking or being traded, and the remaining bedrocks leaving [Jerry and Phil] and being traded [Deron]) while the keys are handed to a head coach that has never head coached and a 50 year old that spikes his hair and has a goatee (and hasn't earned a ****ing thing).
