I'm in favor of Ray being the first domino, since he's the oldest; KG next, when his contract expires; and then Paul when he retires (hopefully as a Celt).
This team was built around the big three, and in three years they gave us a championship, an "if only", and a "near miss".
It's been a great run, but as of now Rondo is our most important asset, and it's time to make the transition to Rondo-ball, because that's where our future lies. Rondo is probably the most dangerous guy in the league in the open court, and we need to surround him with guys who can rebound and run the floor.
Ray has gone from being a most consistent scorer to being a streaky shooter. Streaky shooters are more suited to coming off the bench (where if you're hot you play a lot, if you're not, then not so much). We're not in good position to have Ray come off the bench because we have no one ready to step in and start in his place. Billy Walker would fit the bill nicely if he were still around, since he's a runner, slasher, finisher type (ideal for Rondo-ball). Danny needs to look for someone with those skills, rather than a pure shooter like Ray.
Tony, Big Baby, Nate, and even KG all run the floor well. Paul can still do it all, only in shorter shifts.
Our biggest weakness is rebounding, and it cost us the title. KG's numbers have gone from 9 to 8 to 7 rpg's in his three years here. Perk's numbers have declined, also.
So our biggest need at present is a monster on the boards, who throws a good outlet pass, to get Rondo started in the open court. We need to point Ray's money in that direction.
That's my take on the situation.
