I also think that the Prince signing presages an amnesty buyout for one of the Pistons' big contracts. Who has advocated for Villanueva (net detriment to the team), while I think it might be Ben Gordon (more money, more years). It could even be Rip.
I've had this Ben Gordon trade stuck in my head for the last couple of days.
Ben Gordon to Atlanta(1) Ben Gordon for Kirk Hinrich - start B.Gordon at the point alongside Joe Johnson and let them share the PG duties.
(2) Ben Gordon for Marvin Williams - this was prior to the Prince signing ... Detroit cuts some salary and brings in a younger starting quality SF while Atlanta adds a potent scorer who can either come off the bench (ala J.Crawford) or start (Hinrich, B.Gordon, J.Johnson). Hinrich can cover the two defensively and help hide B.Gordon's D like he did in Chicago.
Also, the whole Tracy McGrady signing which gives them another ball-handler to help Ben Gordon out when he is at the PG position.
Anyway, I would have loved to have seen Atlanta pursue a trade like that. Those guys are far too passive in the trade market. They have good assets. Talent. They should be trying to make a move. Either to add another quality player to the mix or to upgrade one of their stars.
