The clutch postseason player has decided that he wants to play for a school where he can be a more central player, so he's taking his services elsewhere. He arrived on campus at the same time as fellow shooting guards Isaiah Thomas and Scott Suggs, and was behind Thomas from the get-go. With Suggs developing and C.J. Wilcox coming off of his redshirt while every other guard on the roster returns, it didn't seem likely that Turner would be getting more minutes than he received last year.
Turner was pivotal in the Huskies' comeback against Oregon State, scoring 10 points, keeping the game from getting too out of hand in the first half, then making the three pointer that gave the Huskies the lead for good. Without him in that game there's a very good chance that the Huskies would have missed the NCAA's entirely, much less made a run to the Sweet-16. In the NCAA's, he scored 14 against Marquette and 10 against New Mexico, and was among the team's best players in the tourney.
Best of luck in the future, and thanks for your two seasons as a Husky.
