Hawes' left achilles has kept him out of action for the last eight games and Vucevic hasn't played since January 21st due to a strained quad. The rookie appears to be ready to go though after suiting up Monday, and while Hawes probably won't play tonight, he doesn't seem far off. Since neither injury seems to be very serious, it's no surprise the Sixers won't try to make a play for Kaman, whose $14MM salary would make for a tricky acquisition.
With their payroll sitting about $4MM below the luxury tax line, I expect the Sixers to look into smaller moves, perhaps making use of the $2.7MM trade exception they received when they dealt Marreese Speights. Meanwhile, the Jazz, Grizzlies, Spurs, Rockets, Bobcats, Pistons, Pacers, and Cavs are among the teams thought to have some level of interest in Kaman.
