bad fit?
maybe.
worse fit than...,well, who?
if they can't get a player who is in fact a better fit, Turner is a no brainer.
Spurs need dephth at 3 and while he might not be the athleticand tall SF we dream about, he isn't exactly undersized for a 3 either.
he is a decent defender and a good ball handler and he can pass the ball. last time I checked this attributes didn't rule out a player from being a good fit with the Spurs.
after the season Spurs can decide if they let him walk, or make him a RFA. and he accepts the QO, his contract would expire 2015, what fits with the cap/rebuilding situation.
Spurs would only offer their 2014 pick (plus some trow ins) anyhow, so this would be worth the price. and I really doubt the Spurs can get a better player than him at the deadline, considering their possible offers.
