Certainly sounds like he is coming over to play this season. I admit that I am surprised. I did not predict this. I got this one wrong. I thought for sure he was going to be a stash. It will be extra tough on him if he misses summer league. That is a $2.8M cap hold for now and likely a cap hit for the season. For a guy who is probably not ready for the NBA, even for a lost season team.
I guess we can pencil him into the depth chart. JD Davison too as I understand he is signed to a non-guaranteed contract:
White Pritchard Davison
Simons Scheierman Gonzalez
Brown Walsh
Hauser Niang Tatum (IL)
Queta Tillman
That is 13 players and a salary of $203,315,617 by my math. $4,509,383 under the second apron and $15,415,617 over the tax line (with an assumption of what Gonzalez's salary will be). BOS may not sign anyone else to the regular roster. Amari Williams and Max Shugla might both be 2-way deals (if not beat out by other summer leaguers) along with Miles Norris who has already signed a 2-way deal as I understand it.
