Both moves ended up being unnecessary as Boston didn't need the cap space or roster spot as it ended up.
We needed to dump Baynes to sign Kemba.
Not as worked out by doing the double sign and trade with Rozier. Now maybe we don't get to that point without the cap space, or maybe we still do.
Edit: And here's the thing, Boston could have dumped Baynes after the draft if it still needed to. There was no need for urgency at the draft like that, especially at the expense of just dumping a 1st round pick. He did the same thing this year. Just dumped a 1st round pick because he didn't move it before the draft and was left in a situation where he had too many picks. If he would have gotten a future 1st, the trade this year would have been different, but dumping a 1st for two future 2nd's because you had too many picks is just bad asset management.
The Celtics took Kemba in using cap space, even with the S&T. If Baynes was on the roster, we couldn’t have completed the deal.
they gave up 17 million in a trade, they didn't need full max to do the trade. Baynes could have been on the roster and that trade would have still worked
We had half of that counting as outgoing due to Base Year Compensation, and even then it wasn't nearly enough to add Kemba's salary. We absorbed Kemba into cap space, it would have taken a S&T with Kyrie to match the salaries (hence that being a big part of the Horford idea/rumor).
If Baynes had been on the roster, we would have been $5 million short.
you can absorb onky some of. Sprayer into cap space and make up the rest with salary. Are you sure thay wouldn't have applied here?
You can't do that. You can either absorb the player into cap space, or bring them in using matching salaries. But you can't absorb part of a salary using cap space and then match the rest with outgoing salary.
If, at the end of a trade, you end up $100k or more over the cap, you have to use matching salaries instead. There are cases where you could have non-simulataneous trades to bring in one player with cap space and another with matching salaries, but that doesn't apply to bringing in one big salary (like Kemba)
In theory, we could have done a big deal where Rozier went to CHO, Kemba to BOS, and Kyrie to BRK which would have allowed us to keep Baynes, but given that the Nets demanded a first rounder from the Warriors in the DLo/KD deal, it probably would not have been free, or even cheap
