I'm sure they would trade him....but only if they got something better or just as good at a greater position of need. They are allowed to pick this better player and not trade Sexton if you were not aware. I mean, why not see what you have first? Possible Sexton keeps doing what he does, works his ass off and is better than the draft pick and/or Garland.
There are 6 players who put up 24+ ppg, 47-48 or better FG%, 37-38% or better from 3 AND 4+ apg. Kawhi, Curry, Kyrie, Jokic, Lavine....and Sexton
And before you give the usual someone has to score on a bad team there are a lot of bad teams and being the main focus makes it harder to score AND be an efficient shooter.
what's funny to me is there are 3 players who play more like sexton's critics claim Sexton plays than Sexton actually plays - Booker, Mitchell and Young. And these are all exceptional players.
