The teams in the playoffs chose 3rd, 4th, 7th and 8th out of 14 teams. The player chosen 1st overall, was traded, basically, for the guy chosen 6th, and neither made the playoffs.
I think a regular snake worked fine. It comes down to making smart picks and smart trades and yes, getting one of those difference making players. But even getting those difference making players doesn't mean success. LeBron, KG, Steph, Kawhi, and Kobe all stayed home and they were selected 1st, 2nd, 5th, 6th and 9th.
