The Kings have finally come to two realizations in the past year. One, Tyreke Evans isn't a point guard. Two, character and leadership matter. Enter Walker. Not only does he play the right position, but no one in college basketball showed more heart, leadership or a desire to win than Kemba this past season. He has his weaknesses, but he should give the Kings something they really haven't had in a while -- a winner.
None of Ford's testimony is necessarily true; the Kings certainly haven't announced that Evans will not play point guard going forward, given that 'Reke played with Marcus Thornton (a true shooting guard) a lot in the final weeks of the season, with Beno Udrih on the bench. I'll also note that it's unclear Walker will be any more of a point guard than Evans is.
But that said, while I'm not completely sold Walker can translate to the NBA in terms of a high-usage guard, it's a solid pick that would seem to have a serious chance of coming true. The Kings have said they need another guard, and Walker's the No. 2 guard on the board behind Kyrie Irving.
