Oh just stop that nonsense -- I know its popular in certain circles, but it really is ridiculous. The most exciting players in the NBA have routinely, routinely, ended up in small markets. LeBron went to Cleveland. Howard to Orlando. Shaq to Orlando too for that matter. Oden to Portland (and Durant to Seattle/OKC). The Knicks have sucked forever and never gottent aht lucky bounce. Other than through the power of mere repetition through the conspiracy community, you would have an almost impossible task in creating a credible argument for lottery tampering.
And Wall projects out as a franchise PG really, not a SG/tweener like Wade. Amazing physical skills though. But barring a followup disaster next year that might well cost Sacramento its team, the odds are really low we have any shot at him.
