I just don't see very many teams with cap space left that need a center as options for Ezeli. With cap holds, here are what teams have left and who they have at center:
Brooklyn - $23.2M. Brook Lopez ($21.1) and Justin Hamilton (($2.9M)
Philly ------$21.3M. Noel, Embid and sometimes Okafor....logjam at center.
Denver ---$21.1M. Nurkic and Jokic both can play C but at $3.2M combined, not spending a lot on the position.
Phoenix ---$14.4M. Chandler and Len already there. Doesn't seem a position of need.
Milwaukee $13.4M. Monroe making $17.1 but that is about it. Could use another big.
Minnesota -$13.0M. Between KAT, Aldrich and Pekovic, they are stacked at C.
Utah --------$10.1M. Gobert, Withey and Pleiss. Not a real need.

That is everyone else with cap space taking into consideration cap hold or un-renounced Free Agents. Out of that list, Denver and Milwaukee seem like the only teams with current space that also really need a center and would spend a lot of money on one. To go from Golden State to Denver would strictly be a money grab and could Portland possibly lose out to MIL 2 years in a row?
