Spurs are only involved to make the cap work, The Celtics would send Thomas basically for 300k in salary relief to make it work. This trade is designed for if turner wants out of Indiana, as they get 2 first a young player in Nesmith, and decent cap filler in theis who can also play quality big man minutes.

Celtics get a starting center to pair with rob, Turner's ability to shoot pairs him and rob well offensively, and together on defense, they would be unstoppable as both are top contenders for DPOY when healthy.
