Avery Bradley has improved tremendously as a shot creator and overall offensive player.
Marcus Smart despite his inconsistent shooting is a capable PG and a missmatch at the PG position for many teams due to his size and bulk.
Al Horford is one of the best passing big man in the league. I agree, that he isn't the best at creating offense for himself, but in my mind that's mainly because he is so damn timid.
Gerald Green is not a smart basketball player, but due to his athleticism he can create offense for himself, when he is on (he will shoot you out of games, when he is not though

).
The Celtics clearly are a better team with IT. IT is also not a sixth man. He is a bad defender, but so are many starting PG's and the whole Celtics team is built to cover him on that end. Of course missmatches happen and being 5'9 isn't ideal, but there aren't many teams, that have the luxury of an ideal roster.
I mean the Celtics are playing the Cavaliers. A team with 2 superstars and the best player in basketball leading the charge. Before that they beat a strong Washington team in 7 and the experienced but flawed Bulls in 6. Part of that while their best offensive player faced a devastating personal loss.
Really nothing but respect for the run the Celtics made so far.
Ship out IT for whom? A top big man would make sense. Paul George would make sense. Who is gonna play PG for the Celtics in that case?
Smart? I'm a big fan of Smart, because he is a great defensive player, but a starting PG for a contending team? You would need a playmaking big of the caliber of DMC or a SF like George to make that work, so that trades would make sense for the Celtics, but would they make sense for the Pacers or Pelicans?
Fultz? I really don't get the hype every year, before those draftees have played their first NBA game. Every year there are plenty of guys people label as the next "insert current superstar here" with even some added attributes on top of that (Like the next John Wall with a better jumper or something like that). Every year there are of course great players coming out of the draft, but every year they need time to develop and most of those guys fail to reach superstar level. I mean with all due respect for D'Angelo Russel for example, but he is not the next Steph Curry (yet).....
Maybe Fultz will have the same kind of offensive impact IT has currently in a few years (maybe even faster). But as a team already able to reach the conference finals I'm not betting all my money on that and I'm not going to bench or trade my best offensive player for some unproven rookie, just because some analysts believe he is the next NBA superstar in the making. IT is easily a Top-10 PG in this league.Loo Even at 5'9 those are some really big footprints to fill for any rookie. The complimentary players like Bradley, Crowder and Horford are already in their prime. The Celtics only have a limited amount of time to wait for a rookie to develop, when this rookie is given an important role. Billy King gifted them the opportunity to contend, while developing top draft picks in limited minutes. If you aren't able or willing to ship out the picks for another superstar in his prime to really be serious about a championship, why not continue on this path? Develop the rookies in a competetive environment, able to make deep playoff runs and set up your franchise for the time after Lebron and Curry that way, with a small outsider chance in mind (due to some bad injury luck for the Cavs or something like that) to maybe even reach the finals.
From the outside looking in - sounds like a solid strategy.
