You may call them "sentimental reasons", but I believe they are more than merely sentimental. "Cultural reasons", though much mocked and maligned by some posters on ST, seems like a better designation to me - definitely more value-laden than mere sentimentality. But whatever you wish to call the reasons, Pop is not trading Patty this year, for sure. You even pin-point the cultural abyss beyond Mills when you note that LMA would become our senior statesman after Manu and Patty. He is a beta who wanted a trade a season ago - definitely NOT any conduit of Spurs' winning culture.
And you may call White a combo-guard, but he is more like a modern PG. The bottom line, however, is that of the guards on our current roster, he is by far the best PG prospect. Murray doesn't have anything like White's passing ability, court vision or handles. He has to develop skills that White already has. Plus, he is unlikely to ever develop White's innate ability to see the floor. But by every indication White is the odd man out here.
I agree that Walker is a better long-term prospect than Anderson. But they were both supposedly lottery talents.
