The Celtics in theory accumulated a pretty deep roster. On paper, this didn't look too bad:
Guards: Schröder, Smart, Richardson (+ Pritchard)
Wings: Tatum, Brown, Hernangomez (+ Langford, Nesmith)
Bigs: Horford, Timelord, Kanter (+ G.Williams, Parker, Fernando)
However, some guys individually have disappointed so far like Pritchard, Nesmith, Hernangomez

and Kanter.
And besides that it turns out that not unsurprisingly there's a lack of balance in playmaking and shooting.
In practice this teams seems years away from contending. And to be honest I think that's true.
So I come back to what I have been advertising for the last two years to focus on developing our drafted youngsters.
Get value if you can get it for Schröder, Smart, Richardson, Horford and Kanter. Let's play Pritchard, Langford, Nesmith and Grant Williams a lot of minutes, there's still untapped potential there and foremost we need to build up value by them as assets.
The big question is whether we should break up Tatum and Brown, but I don't think there's a reasonable deal to be made that would be worth it. I doubt very much we could obtain Young, Morant or LaMelo Ball for Brown.
I'd keep an eye on Cleveland about Garland or Sexton and likewise Sacramento about Fox and Haliburton, but I wouldn't give up Brown for any of them.
