Seriously though, the Spurs weren't in that much luxury tax hurt. All they needed to do was salary dump Butler (Butler + a pick somewhere for nothing), salary dump Beno (like they did), not re-sign Bonner and sign Scola and they would have made it under the threshold. It wasn't like they were in dire straights and trading Scola was their only way to reach salvation.
Perhaps the Spurs wouldn't have had the money to sign 75,000 D-League players for cups of coffee during the year but I think they would have survived.
