As things stand now, in my opinion, our best four players are Isaiah Thomas, Marcus Smart, David Lee, and Amir Johnson.
Since the team appears intent on being as respectable as possible this year, maximizing playing time for those four players -- together, ideally -- makes sense.
The gaping hole, of course, is at small forward.
What is the Celtics' best option to complete that 5 man unit? Turner and Crowder are both unsatisfying solutions. Can Jerebko be a starting small forward? I rather doubt it, though he averaged basically 15-10 on great shooting numbers per-36 last year in his time with the Celtics. He mostly played at the 4 and 5, though.
How about Gallinari? I like the idea of adding a creative shooter with good size at the 3, but at this point Gallo seems less likely to adequately defend at the 3 than Jerebko.
That's kind of the problem of this 4 man grouping: with Isaiah Thomas and David Lee on the floor together, you really can't afford to have anything less than stellar defenders at the other three positions.
What do you think of as the ideal (non-superstar) wing to complete this unit? I think Brad Stevens's old buddy Gordon Hayward would be perfect, but he's not going anywhere. A 3-and-D guy like Trevor Ariza strikes me as the baseline.
