I disagree. What you need to win championships is lebron, giannis, kahwi, steph, jokic. Doesn't really matter all that much who we trot out at point guard. Could be george, tht, dunn, sexton, etc and if we aint got that top 5 (often top 1) dude on the roster then we aint winning a chip.
Sexton at point guard isn't the problem. I think sexton could have started at point guard and won a chip on the lebron heat team, the lebron lakers team, the nuggets current team, the giannis bucks team, or the durant/steph team. Jazz team isn't good enough to win a chip. Doesn't matter if Sexton is our starting point guard, is coming off the bench as a combo guard, or is not on the team at all.
