Altho i'd have preferred if his epiphany had come against another team, it does seem like SGA's experiment of trying to spam iso 3s has ran it's course. Simply having the 3 ball as a threat is enough when you're the primary ball handler with a team loaded with spot up shooters.
Granted, without the 3 ball he's never going to have those highs of 50, 60, 70 point explosions like Luka, Tatum, Mitchell etc do... but he also wouldn't have the lows of their stinkers when the 3 ball ain't falling. Hence why he led the league in most 30 pt games last year but only had a handful of 40pt outings.
