Should Hawks be buyers or sellers post-Krejci trade?

Krejci's trade makes sense after acquiring Kispert, netting two 2nd rd picks despite a team friendly contract is a quality return too...but given Duop Reath is out for the year and the Hawks currently 0.5 games ahead of the Hornets for the final spot in the play-in, should the Hawks be buyers or sellers ahead of Thursday's deadline? Some smoke that the Hawks could make additional moves as well
