I think its a different kind of mins issue. I think he doesn't want to play any until the All-Star break.
I wonder if this type of thinking will eventually backfire. P.J. Brown was a relative success story after a long layoff. Starbury was an abject disaster as a player, however. Six months without playing probably is going to have a negative effect on almost any player's game.
If Wally sits out, I think there's a chance that teams say they have no interest in an all-shoot, no defense guy whose skills are already in decline. With Wally's current negatives, why would a team want to add "rusty" and "disrupting team chemistry" to the mix?
