Rajon Rondo, Ray Allen, Paul Pierce, Kevin Garnett, Jermaine O'Neal
Jeff Green, Delonte West, Courtney Sims or Sean Williams, Troy Murphy, a veteran point guard comfortable with being a career backup
Avery Bradley, draft pick, draft pick, D-Leaguer, undrafted free agent
Roll the dice on young, untested players instead of veterans. Look for the next Wesley Matthews or Landry Fields instead of hoping for the next Bill Walton (a veteran who can be a huge boost....if healthy). Pack the roster with enough of them that Doc will be forced to play some.
The Celtics won't get a top free agent and probably have nothing that allows them to trade for a lottery pick. Build a young, hungry, athletic bench and hope someone breaks out as a super-sub.
Above all, hope that labor strife doesn't lead to a shortened training camp.
