Because Rondo's contract expires in a two years, he will demand max dollars, and Boston still won't be a contender. By the time Boston is ready to compete again, Rondo will be on the wrong side of 30 and no longer young and improving. And that is if Boston doesn't have any misses in the draft and ends up with at least solid value.
No offense, but I don't think anyone here has the slightest idea of what Boston's plans are going forward. Are they going to use all of their draft picks? Are they going to trade them? If so, for what? Also, the odds that the Celts buy into the "hang around at the bottom of the league until you land a superstar" mantra that so many here espouse are fairly low.
I'm beginning to think that you have the right of it here. I think that the Cs are going full in for the tank this season. That's just looking at the roster. But after that, I doubt Danny really wants to spend a second year in the basement. This draft is worth it, and any time you can pick Top-3 you should be picking up a cornerstone, but this year especially seems worth it.
After that, only Gerald Wallace's albatross contract stands in the way of making a quick transition to playoff lock. A good signing here, growth from some of our guys there, we could be okay. Not contenders, but not terrible.
Here there is a bit of a double edged sword regarding Rondo. If they were going to trade him, maximum value would be hopefully at the trade deadline, but more likely in the offseason. But what if Rondo comes back averaging 20 and 10? It's doable, moreso if he uses his time off to hone his skills and turn that chip on his shoulder into a resentful razors edge.
He's basically a reliable (I'm talking 4-5 attempts and 38%) 3 pt shot and 75% on at least 4 attempts from the line away from 20 ppg now, and while he's no longer a spring chicken, he's not beyond taking his game to a new level at 27 years old.
