I am talking as a point guard, not as an overall player.
Of course, if I could have Barton from his prime on my squad right now, I would take him in a second, and give up every draft pick and GM point for the next 3 years.
In fact, now that I have truly done the calculations, it is his 3rd best year in Assist to TO Ratio.
in 2013 and 2017, he had an above 5:1 ratio... This year he has a 4.6:1.
Team is 15-6 with him starting this year... The true measure of a player
