they signed some German guy and just signed Baynes from Detroit for some front court depth
Dj should make the team if he performs well before the season started. There is talk they may look at vet min players to add some depth however. Gasol was not something they can do now. I think they would have to trade Horford to make the money work, along with some top other pieces, and I dont see that happening. If during the season Gasol's asking price from memphis drops and Boston continues to need help in the middle I guess it is something they might explore.
Yabu should be on the team unless more vets are added. As of right now its assumed he is on.
