Schroder at $6M is a great signing. No doubt. Gives us a surplus at guard now though so it seems like someone will have to go.
Trade Smart: Schroder, Pritchard, Dunn is a fine PG rotation. No longer a need to play Smart at PG. For SG/Wing, we have Brown, Richardson, Nesmith, and Langford, plenty of depth. I still like Smart but he is now very expendable from a roster standpoint.
Trade Richardson: Same logic as above but instead of trading Smart, you trade Richardson. Richardson is probably better suited for the SG/Wing role than Smart who leans more PG/Combo.
Smart for Markkanen. Good trade if it wasn't for the hard cap plus CHI has plenty of guards, just spent big on Ball, so I don't see the fit for Smart. Hard time seeing this happen but intriguing.
Richardson for Bagley. No hard cap. More questions with Bagley. Richardson is probably more suited to the resulting role on the Celtics (SG/Wing) than Smart, keeping Richardson and getting Markkanen is probably best from a roster balance standpoint. Keeping Smart, getting Bagley does address our PF dearth.
I strongly doubt Dunn will be here come the start of the season. We have to drop to 15 rostered players. I think our depth chart will look like this:
Ball Handlers: Smart, Schroder, Pritchard
Wings: Brown, Tatum, Richardson, Nesmith, Langford, Edwards
Bigs: Horford, Timelord, Kanter, Gwill, Parker, Fernando
Gwill is kind of a floater, I'm not really sure if he's a wing or a big. Richardson can probably handle the ball if needed but he's not going to do that fulltime.
Just my opinion, and it will probably be unpopular for those of us (including myself) who grew up watching the original Celtics Big Three of Bird, McHale and Parish in the frontcourt, but the whole power forward vs small forward argument I think is probably anachronistic in this era...you play to your strengths and to take advantage of the opposition's weaknesses. I feel like most coaches want a switchable lineup who can defend multiple positions, rebound, handle the ball (some better than others) and stretch the court. If you have a Tim Duncan style power forward with a solid traditional center, you play a two-big lineup. Or if you don't, you play your power forward as your main big. Unfortunately we don't. The only two bigs we might want to play together would be Horford and Timelord (for certain matchups) or Gwill with any of the other bigs. Otherwise I think it's ball handlers, wings and bigs and Schroder adds nicely to our depth.
