I'll go with my dream realistic off-season:
1. Sign Antonio McDyess, Grant Hill, and Quinton Ross (MLE, LLE and minimum salary)
2. Resign BBD, Starbury, and Powe.
3. Let Pruitt and Moore walk.
4. Trade Tony and Scal for Nocioni.
Roster:
Perk / McDyess / BBD
KG / BBD / Nocioni / Powe
Pierce / Hill / Nocioni / Walker
Ray / Ross / House / Giddens
Rondo / Starbury / House
To me, that's a "win now" team, that still retains its key pieces for the future. It's also a team that we could put together using our current cap exceptions.
Can't think of a much better use of the exceptions and trades to address the team needs, Hobbs. McDyess is a personal fave of mine, and Ross is the defensive 2 we need.
One thing I wonder about this dream scenario: would some of these free agents agree to sign with Boston, knowing they'd probably only see 10-15 minutes a night? Would Baby resign with Boston if McDyess was lined up to share backcourt minutes, and vice versa?
A five man frontcourt rotation between KG, Perk, McDyess, BBD, and Noc, three guards in Ray, Rondo, and Marbury, and Hill (and Noc) backing up Pierce, makes us 10 deep. Ross and House see time depending on game situations (one for offense, one for defense). Might be tough to keep people happy, minutes-wise.
I imagine Powe, Walker, and Giddens all wear suits for 90% of the time, barring injury to a starter.
