I think it is becoming common knowledge that Kevin Garnett will come back to the Celtics next year; there is no transcendent BIG in the draft and a two million dollar deal worth say $10MM per seems reasonable. Besides, it is clear that he is the "ethos" that makes the Celtics the Celtics.
It is less clear on Ray Allen but I think circumstances (his bones spur injury) make the probability higher. First, Allen is going to need off season surgery and that will drop his market value considerable to someone just wanting to have a hired gun, which I do not think Allen wants to be. He can easily be the sixth man in the Celtics system in which he is a known commodity with a team and coach that he trust. I think you sign Allen for say $3.0MM with a player option for the second year and perhaps a no-trade clause if he goes for a hometown discount. But we should move to staggered minutes for Ray like we are doing for Kevin Garnett. i'd rather have ray Allen be a sniper for us rather than somewhere else; and I think the injury give him a perfect opportunity.
Clearly we have to move Avery into the starting line-up and I am not sure Keyon Dooling is with the team next year as I think we have to bring ETwan Moore along. Not saying that we give up on Dooling (love his locker room presence and professionalism) but Etwan needs to get those minutes; I think Moore can learn a ton from Ray Allen, Avery, and Rondo for the rotation.
After looking at what is out there for free-agency and in the draft (in terms of transcendent players) I say that we bring along the young talent with the Big Three in toe for two more years (end of Paul Pierce's contract).
