It's going to sound nuts, but here's what I do:
Start T'Will at PG against Felton:
Physical enough on D to body Felton, and can make entry passes and handle ball. Upgrade from Bradley in this match up.
Use JET to backup PG against Kidd:
No speed mismatch on D, keep Kidd honest (out of passing lanes) on the other end.
Start Pierce on Prigliioni at SG:
Most firepower. Use it.
Bradley/Lee backup SG and take turns at JRSmith. They're our best SG defenders; they should be able to keep him honest enough, even though he's 6POY.
Green starts SF:
Again, most firewpower. Pierce backs up.
Bass on Melo:
Bass works his tail off, but can only be expected to go 24 mins or so.
Green & KG split remaining 24 mins backup PF, including a stint of KG on Melo.
KG starts at C for 24 mins.
Backup C duties: Need a help rim defender and rebounder.
Candidates: Wilcox, SRandolph, DJWhite.
Winner, Doc: Bass
Winner, me: Wilcox or Shav
That's the matchup strategy: lots of guys playing high energy perimeter defense, with our best playing there best with plenty of rest, and a solid interior rebounding presence. That's how we win.
But Doc won't start T-Williams and will stay with Bradley, who Felton has pushed around and struggles to initiate an offense, and Bass will continue to play center, so we'll have no interior defense, rebounding, or rim protection when KG is out.
That's how we win (or lose): matchups at positions in possession games.
