The Celtics have what most consider to be the best “top 6” in the league. Hauser and Pritchard have been solid rotation guys. Beyond that there’s a lot of question marks on the Celtics bench.
So according to Shams, you can expect the Celtics to be ready to make moves to beef up the bench.
The Celtics have a $6.2 million TPE that they can use to recoup salary without having to trade any players, as Keith Smith has pointed out. Locating someone who would make a significant difference within that pay range is the tricky part. Furthermore, when figuring the tax bill, adding salary at this point would count three or four times the salary. In a perfect world, the owners would approve the additional expense if there was a clear upgrade. Which players meet that description, I’m not sure.
You must think about which players you would be willing to trade away if you aren’t using the TPE (and 3-for-1 deals are difficult to complete in season while teams still have roster constraints).
