If you look at this in terms of who actually contributed last season as compared to the current state of things, this is the net:
Out: Smart and Grant
In: Porzingis and Brissett
Gallinari and Muscala did not really contribute to the team last season. They may have contributed this season but you can't really count either as part of the team last season.
Just looking at that, I think we are better. I am not real sure what to expect from Brissett but in 2021-22 he played about 23 min/gm over 67 games, averaged 9 pts and 5 rebs with 35% from 3. He was down on all fronts last season and I don't know why but he is not that far off from Grant in any case. And an inch taller. I don't think his natural position is PF like Grant, we still probably need a solid bench PF to replace Grant, but hopefully, Brissett is a useful rotation player, like Grant.
And the thing is, we still have from 2-4 roster spots we can fill in or upgrade. We should still be able to add something useful to the roster.
