The best thing to do with the cap space would be to trade 2-3 of our guys for an expensive singular talent. We don't even have to do that during the summer. We can just hold onto the space until mid-season and take a look at the landscape. I like the patience Ainge has shown so far in not reaching for guys that aren't actually going to make a difference.
This is 100% incorrect. The Celtics only have temporary cap space, created by delaying the signing of Jae Crowder and the trade of David Lee. Both of those things will happen before the start of training camp. Had they already happened, the Celtics would be $5-6 million over the cap. It is not for use during the middle of the season.
Yep.
So it seems a shame that they lost the trade exceptions because they were under the cap, is that the tradeoff for not signing guys sooner?
I think what we got for it is more valuable than the trade exceptions we had (Amir's, Jerebko's, and Lee's contract).
They add more flexibility to potential trades (can match-up to higher salaried guys while the exception could only be used on guys that fit within it), and I see the TPEs as more valuable during free-agency than during the season, so having this big contracts extends the trade window (availability during trade deadline, the draft, and next year's free-agency in the case of Amir's and Jerebko's).
Of course, there are some trade-offs (can't provide the financial alleviation to other teams this year as a TPE would, but can still provide it for future years for example), but in general I think we're better off.
Keep in mind also that we could've manufactured cap space in excess of our biggest TPE if we wanted to during this free-agency period (about $16M or so in cap space). That there was nothing to be had at this moment should give you a hint that the TPE wasn't going to be of much use at this moment. And this was after agreeing to Amir and Jerebko (but before agreeing to trade for Lee).
We also got a 2nd rounder and PJIII using our cap space as well, and not sure if I'm forgetting any other assets we've acquired this Summer.
And that second rounder, not sure if protected, could be a very good one since it belongs to Detroit.
