Nope, because the only rookie I see getting minutes off that bat is Tatum, and the others will have to really earn it and outplay veterans.
Between Horford, Baynes, Morris, Crowder, Hayward, Brown, Smart, Thomas, and Rozier that's 9 rotation spots, and that's not even including Tatum or even Theis who is a Euro league veteran.
The way I see it Ainge has kind of 2 rosters, one built to win more now, and one to develop for the future. Of course a few players like Brown, Smart, and Rozier overlap that but they have all proven worthy of some rotation minutes.
