The short leash is what makes him so efficient. It's really his only saving grace offensively. He can get a bucket. Does it help the team all that much? I would say it has this season, because he has been extremely good in that scoring efficiency department, but I dont see much room for growth from Sexton (unless he takes a sizeable uptick in 3pt volume, but that just isnt his game and his form doesnt really allow for it). This is his peak. You make him the lead guard and his efficiency will go down and his lack of making others better will still stick out like a sore thumb. The juxtaposition between him and Conley really is a joy to watch, makes you appreciate Conley sooooooo much more. Hardy deserves COTY for the job he has done with Sexton tbh, especially if Ainge is able to parlay that into serious assets.
I mean, you really care about RAPTOR stats dont you? Because it was all the rage in the Bones defense discussion. Conley is 2x the player Sexton is according to RAPTOR, and that's with Conley going through long spurts of being injury riddled and just generally being a very mediocre scoring efficiency player.
The fact that Sexton is so efficient offensively from an individual standpoint, and yet he is barely an offensive + to the team should tell you all you need to know. Hopefully the Jazz can sell high on his basic stats looking so good to the layman eye.
