We're at roughly $60M now for 13 players, and still have the Rondo exception in play ($12.9M). I believe we need to renounce Bass and Pressey (which seems obvious with Jerebko, Johnson and Rozier on board) before we use the exception.
So we could spend around $9M +/- moving Wallace or sending back salary. That's enough to sign Crowder, if we go that way.
For Harris, we could do a S&T with Orlando where his salary starts at $12.9M / year, and send back cash and/or picks. Ditto for Draymond Green. Or we could S&T Crowder for them?
If we utilize our space to sign Crowder, and do a S&T we could still be adding a $12.9M annual player. If we move Wallace we have max money (depending on the service years).
I think, signed amateur cap analyst.
