Obviously, we never know when Danny will make a surprising move, or if anybody unexpected will earn a spot in late season or the playoffs, or where the picks land and who we draft (if the C's draft 3 centers, maybe they plan to part ways with Time Lord, 3 PG's would obviously hurt Edwards and Waters chances of returning) but this is how I see it:
Returning:
1. Kemba
2. Tatum
3. Brown
4. Smart
5. Langford
6. G. Williams
7. R. Williams
8. Theis - team option picked up
9. Ojeleye - kept
10. Hayward - either opts in or extends
11. Waters - given Wanamaker's spot
??. Kanter - opts out, will test market, maybe gets full mid-level for 1 year, but open to returning if Danny matches money
TW. Tacko - either offered another 2way or someone else gives him guaranteed minimum contract.
Out - Poirier, cut or traded away for a non-guaranteed contract or top-55 protected pick + cash, like how the C's got rid of Bird, Nader, Melo, etc.
Out - Edwards, same as Porier
Out - Green, cut
Out - Wanamaker, not re-signed, maybe gets a slightly better offer than 1 year min that Danny might again offer from another team.
If it plays out like this, the C's will have 3-4 spots open depending on what Kanter's market is, which leaves options with the draft picks. The C's can draft 4 guys (2nd rounder gets a TW) and see who sticks, or can try to consolidate 2-3 picks to move up a couple of spots, trade 1-2 firsts for a future first, draft-and-stash, etc.
