I see a lot of midtier, mostly overpaid players. Johnson is good but I want nothing to do with that contract even if you get him for free (he gets $21.5 mil at age 33, $23 mil at 34 and $25 mil at 35; right now, at 31, he's barely an All Star in the East). Amare's contract is toxic and uninsurable. Ben Gordon is a 6 foot tall bench scorer paid like a core starter for two more years. I'd want at least two first round picks to take any of those guys. Odom is an inconsistent, aging headcase who needs to be in LA or Miami, as he has said. I'd much rather keep KG than bring in Odom. And to use cap space for outside players - via trade or free agency - you have to renounce your Bird rights to at least some players.
Nene is pretty good right now, but seems to be regressing and is getting $13 mil a year for four more seasons after this one, when he's 30, 31, 32 and 33. And I don't think he'd come free - the Wizards just gave up McGee to get him. I like Wallace enough but he plays the same position as Pierce and Jeff Green and New Jersey just inexplicably gave up a top 10 pick to get him.
I like OJ Mayo, too, if you can get him fairly cheap. But he's a restricted free agent, which means your probably have to overpay him on a long term deal to steal him. I don't want to risk overpaying a guy who doesn't even start and being stuck with that for 4 years. And you're giving up your Bird rights on your own players to do that.
Jefferson is intriguing, but it depends on the price. He has an offensive post game the Celtics could use, and I think Garnett would help his defense tremendously. Totally agree, though, with snively, that if you go for Jefferson, it's to team with the older guys on our roster as the new addition to stay in contention. (He's well above 2010-11 Shaq in ability, though, and would be much more than a fifth wheel.)
That's why what cuts at me is that they would've been much better off pushing for a move like this at the deadline. Financially, they could have tried Jermaine, Wilcox, Dooling, Johnson, Daniels, Moore and a first rounder (lesser of ours and Clippers) for Al Jefferson ($14 mil this year, $15 mil next) and Earl Watson ($2 mil this year and next). Then you get a 27 year old center who can rebound and give you a post scoring option for this year's playoff run (something that gives you a different dimension for other teams to have to prepare for), and his defense could improve a lot playing with KG. Al replaces Bass in the starting lineup, improving that group, and your bench gets a big boost when Bass is added and a small boost from Watson replacing Dooling.
Or, as another option, Emeka Okafor. He's owed $13.5 and $14.5 mil the next two years, about $4-6 mil a year more than he's worth. That's the type of contract you get assets to take instead of giving assets to acquire. Jermaine, Wilcox, Dooling, Daniels, Johnson and Moore for Okafor, Greivis Vasquez and Minnesota's first rounder, and you push for Xavier Henry. You might not have had to include Johnson, but I have no problem throwing him in there since he's not in the rotation and if at age 22 he can't get into a short rotation on an aging, borderline playoff team in a compressed schedule season, he's not a special player and it's worth using him to upgrade to Al. Celtics grab a pick likely to be in the 10-14 range (Jeremy Lamb may become a possibility), a big who defends and rebounds and an actual ballhandler off the bench (I think Vasquez would benefit from playing with Bradley since Bradley can defend point guards, Vasquez's biggest problem).
Keep in mind, to use their cap space this summer on one of these guys, the Celtics are gonna have to renounce rights to at least some of their free agents. Then your team is basically Pierce, Rondo, whoever you acquire, minimum contract players and picks. So you don't want to give away draft picks to get them now. Honestly, I'd rather keep what they have on cheaper contracts and have Garnett and Allen mentor the next generation. Garnett makes bigs better at defense period. Allen's work ethic and healthy habits may rub off on younger guys (particularly if the Celtics can get in position to grab Lamb).
Had they done one of those trades in season, though, their cap space would be drastically cut - by $14.5-15 mil trading for Jefferson and Watson (add $17 mil, subtract $2-2.5 mil for Johnson and the first rounder) and by $15.5-16 mil by trading for Okafor ($13.5 for Emeka, $2-2.5 mil for Minnesota's first rounder, Johnson and Vasquez cancel each other out). So they would only have about $10-11.5 mil in cap space this summer, and if it was Okafor, they would hurt their cap space in 2013. But there are no marquee free agents coming to Boston this summer anyway, and if a great opportunity arises in the summer of 2013, they can always amnesty Okafor. Plus, instead of using the $10-12 mil on outside free agents, they can just resign their own players - Green, Garnett, Allen, maybe Bass (depending on what they draft). Suddenly they're rolling out a starting five in the playoffs and probably next year of Rondo, Ray, Pierce, KG and Jefferson/Okafor, with a bench of Watson/Vasquez, Bradley, Pietrus, Bass and Stiemsma/Hollins. Next year you replace Pietrus with Green (or sign and trade Green and try to keep Pietrus with the midlevel exception). And you add either three first rounders if it's the Okafor trade (my realistic hope if you had say 12, 17 and 23 - Lamb, Royce White and Arnett Moultrie) or only one if it's the Jefferson trade (White or Moultrie) and a second rounder.
You have a strong starting core, a much deeper bench, and lot of young players (at the start of next year, Rondo and Green will be 26, Bass 27, Bradley 21, your draft picks 19-22; Okafor will be 30, Vasquez 25, Jefferson 27). Boston can stay below the luxury line with proper planning, has young assets and enough big contracts expiring in the next year or two to make a trade if it comes up.
Now, though, I just don't see the point of giving up cap space, a pick, AND the right to bring back at least a couple of their own free agents to go after a guy like Jefferson. Better off signing short term deals, keeping your picks, trying to develop young guys, and waiting till 2013, maybe you sneak in and grab a 28 year old Jefferson as a free agent.
