Well, if you want guys who fill lanes, you have to start by benching Pierce until he can run again.
As for Joe Johnson, you can't pick him up unless you are under the cap or if you have assets that Atlanta wants in a sign and trade. We do have an asset they would want: Rondo. Are you willing to give him up for Joe Johnson?
Brick,
I'm not sure if the JJ comment was directed toward my post or someone else, but to answer the question, I would not want to trade Rondo for JJ because I think the best idea is to pair the two players. In my trade proposal, I think the C's get sufficiently under the cap to offer JJ a max, or at least near max contract such that if rumors of him wanting to get out of the ATL are true he could join a very good situation with the C's. The C's would have Rondo, Ariza, KG, and Perk on the books this summer if they trade PP, Sheed, and Baby for T-Mac and Ariza, let everyone expire, and decline to pick up Walker. That leaves roughly 39 million or so on the books. The cap is a little over 59 million this year. Say it drops 3 million next year to 56 million, which leaves roughly 17 million for a free agent max contract (enough for someone like JJ). Then, the C’s still have bird rights on Ray, Tony, Eddie, and T-Mac, two picks, and a mid-level exception to round out the roster. There might be something I'm misunderstanding, but I think obtaining JJ is possible under this scenario. This would also leave the Celtics with total yearly salary that is much less than it is now with all players except Perk locked-up for several years. Like I said before, trading Paul is unthinkable; however, if the window is closed, trading him is the quickest way back into contention.
