Expecting very little. Stevens has decided to go with one big lineups the rest of the way. Timelord and Thompson will be those bigs. Fournier will get a bunch of swing minutes, while Tatum and Brown will be guarding PFs a lot more.
Wagner will be the emergency big if something happens to TL or TT.
If you can re-sign him cheap for next year, I would rather have him as a developmental big on the roster than Tacko.
