If its true, I would say there is a chance Parker could be traded for a bigman, I guess Howard if he accepts to re-sign. The Spurs could absorb an bad contract, sending them Jack for example.
Parker, Jack, Splitter, Cory and Blair for Howard and Hedo
De Colo, McCalebb and Mills could do a decent job at PG, while the bigman rotation of Howard, Duncan, Diaw, Bonner and let's say K-Mart would be quite dominant.
De Colo / McCalebb / Mills
Green / Manu / Neal
Leonard / Hedo
Duncan / Diaw / Bonner
Howard / K-Mart
The Spurs would change from a perimeter oriented offensive team to a team with strong interior presence, both on offense and defense.
