Do NBA head coaches even need to be good at X&Os?

[iamgine]

Of course they can't be completely ignorant but it seems to me they got a bunch of assistant coaches who are just wizards at X&Os. Like Nick Nurse, guy was an assistant for years. Best bet he knew his X&Os way before he became head coach.

Xs and Os

The worst coach ever in terms of the first two I've seen is Doc. That's why he's choked so many 3-1, 3-2 series leads. At some point, that rah, rah stuff doesn't work and has to be replaced with legit adjustments.

Like any great leader, a coach must have a vision

They need a vision for the team's style of play - aka which style will maximize chemistry and teammate fits, so each guy can "play their game" and have maximum impact.. This might require some guys taking a step back for the overall synergy of the team

these things require a high-level understanding of each player's skillset and capability.

Once a head coach has a good vision for the team, part of remaining job becomes delegating to assistants to make it happen and trouble-shooting when obstacles to the vision arise.
