As the MassLive article points out, most of the guys we might have wanted in that Hernangomez TPE will fit in the Schroder TPE, which they'll have until the deadline. And even if they don't use it, Celtics have the best record in the league and should be frontrunners in the buyout market.
It remains the dream to pry Vanderbilt away from Utah but even if that doesn't happen, I'm unconcerned.
No reason not to use both.
No reason to use both, either.
Using a TPE just to use it is not a good reason to use it. If using both resulted in two good deals, then sure, use them both.
Even if they didn't have the second TPE that expires later, I am not sure that they would have used the first one. I think if there was a good deal to be had, they would have used it, whether they had another one or another 3.
They probably are not going to do anything with this TPE either, at this point, it seems more likely that they pick up a vet who gets bought out after the trade deadline.
