Possessing the 14th, 20th, 22nd and 51st picks in tonight's draft, as well as the 2020 Memphis pick on top of all of their own, Boston could do both.
More probable, though, is whatever path brings more value to the Celtics' new direction, their youth movement. With Kyrie Irving and Al Horford almost certainly on the move, and Aron Baynes likely joining them, look for a veteran big to be a target in free agency, though possibly in the range of the non-taxpayer mid-level exception.
However, if the right move is there, the team might offer most of their remaining cap to a big who fits Boston's age curve and style of play. As of now, the team can get to $23 million in cap room by moving Baynes into another team's cap, and could get to almost $38 million if they renounced all their free agents.
With a respectable warchest to sweeten deals and a league in looking wide open with the Golden State Warriors likely hobbled with injuries next season, the range of outcomes tonight is so wide, it's hard to divine what Danny Ainge could be considering.
Boston has offered center Aron Baynes -- $5.4M expiring contract -- into salary cap space elsewhere, league sources tell ESPN. Without Kyrie Irving and Al Horford on the books, moving Baynes without taking back salary could get the Celtics to $23M in space.
