Right now we cannot offer any player (not counting Tony and Jam here) more than 3M (approximately), which is the money we have left from the MLE.
I guess they'll use that money to sign Rade, Brooks and Rabb, as second rounders don't have a rookie salary scale.
This year you have to count on the two additional spots for the two-way contracts. Assuming Kobi Simmons will get one, maybe Wallace signs Brooks or Rabb to the other one.
Although I think there is a trade coming. Too much backcourt players on the roster.
