Fultz, Ball, Smith, Ntilikina, Monk ...
Dollars to donuts, the 2017 BRK pick is going to be a point guard.
Unless the Celts can find a trade for a superstar (i.e. Butler, George, Cousins) that involves the pick, they're gonna have an elite point guard prospect behind Isaiah Thomas.
. . . and that's fine.
Since 2000, the highest WS total for a rookie point guard was Chris Paul in 06-07. He was by far the outlier. The next closest was Damian Lillard with 5.8, and he played zero defense.
Isaiah Thomas had 9.7 WS in his first full season as a Celtics starter, and he's currently on track for 12-13.
Unless the Celts don't care about winning next year, starting a rookie point guard isn't a great idea.
Point guards take a while to develop. There is nothing wrong with playing an elite guard prospect 20-24 mpg for a few years while the team figures out what sort of player they can become.
It will mean, however, that either Smart or Bradley will need to go. That might be difficult, but it may help the Celts address the weakness in the frontcourt.
I'd rather trade Smart, but I have a feeling he has no trade value. You could get a great return for Bradley, but he's probably my favorite player on this team.
I think Smart has positive trade value, but I also think it's safe to assume he's not a blue chip piece anymore, if he ever was.
As for Bradley, I have been really impressed by how much he's improved himself over the years. He's a crucial piece for this team, and as the longest tenured Celtic he's a leader.
With that said, I think the SG spot is the next most obvious place for an upgrade after PF (Amir).
Bradley is a more valuable player than Crowder this season. However, because Crowder is locked up on a cheap contract long term, it will be much easier to keep him and try to upgrade elsewhere. Having a quality starter on the wing for cheap makes roster construction so much easier. Bradley, on the other hand, will likely get a very lucrative deal in a year or so.
As much as I like Bradley, he's not irreplaceable.
Thomas, on the other hand, is pretty much irreplaceable. He's an elite pick and roll ballhandler and scorer in a league where having such a player is the essential requirement for your team having any sort of chance at doing something in the playoffs.
While the Celts may get another player of that sort in the draft this year, as I've already explained it will take time for that guy to become ready to take the torch from IT.
All of that adds up to Bradley being the most obvious option for a trade. The team could still opt to trade Smart, however. He will also be due for a raise in 2018, and while he doesn't have a lot of trade value, he could still be a piece combined with other lesser pieces that turns into a useful rotation big.
