I never thought Boston was a contender, but this team will be fine and finish anywhere from 3rd to 10th in the conference. That is where this team will end up because that is the quality of the roster on the team. Tatum will get to the mean and the team will win more. Ime will figure out that Smart is not a PG and will stop playing him there. It will all balance out and barring some major injuries the team will win somewhere in the 45-50 range of games.
Smart's not a shooting guard either.
Smart plays just fine as a 2 guard. He isn't a shooter, but plenty of SG's in history haven't been shooters. You don't need that from the position.
Schroder, Smart, Brown, Tatum, and Horford should be the starting 5. I really don't understand why Ime doesn't see that.
I also really think they need to shorten the rotation for the next few games and get the team back to winning basketball (and more than just against crappy Orlando). I'd do something like this for the next few games
PG - Schroder 30, Smart 18
SG - Smart 12, Richardson 24, Brown 12
SF - Brown 24, Tatum 24
PF - Tatum 12, G. Williams 24, Horford 12
C - Horford 16, R. Williams 32
Get the team set up well rotationally and win some games. You start winning, you start sprinkling back in Langford, Nesmith, Pritchard, Parker, etc.
