What if the Celtics were able to get Portis, too. If Boston adds in Garza the numbers seem to work.
Starters: White, Hauser, Tatum, Portis, Giannis
Bench: Pritchard, Scheierman, Harper Jr, Gonzalez, Walsh, Queta, Timelord(FA signing), Vet FA? (Beal, Bruce Brown, Trent Jr, T. Prince)
Portis is a very good shooter and he brings toughness. Career 48% from the field, 39% from 3pt.
Bobby is 6?9/250lbs, so he can play minutes at Center as well. Feel like that would be a top team in the league.
