Sources: Celtics shopping Marcus Smart, Jae Crowder, Avery Bradley to make room for Gordon Hayward

This is one possible way to get the money for Hayward.

It also dovetails with expectations I posted in the "Which player is traded, Bradley, Crowder or Smart?" thread. Unfortunately, it's probably not just one, and could be all three.

Be it to make room to pay Hayward, or to deal for a big, at least these three are going to need to depart.  I could also see Brown substituted for Smart.  I'm not calling it this way because I prefer to see these players depart, it's just the logical conclusion looking at the roster, cap, and bringing in Hayward.
