How much does NBA head coaching matter compared to other sports?

There are many professional team sports played at the highest levels. The ones that come to mind are:
1. American Football
2. Baseball
3. Basketball
4. Ice Hockey
5. Soccer

In the various Kawhi threads, a lot of people are giving Popovich a lot of credit for being one of the best NBA head coaches of all time. But I wonder if the real credit should be the GM for their awesome drafting instead.

That led me to wonder, the extent to which the head coach/manager matters.

Let's take a "median talented team" in a given sport. So not a team full of scrubs or superstars. Let's imagine, if we can, a "median quality coach", if that's possible. How much difference can the supposedly "best" head coach really make in a given team sport over a "median" coach (with a median-level talented team)?

(Note that I am speaking only of coaching, both on and off the floor, including practices and such. Do not consider coaching contributions via influence in off the floor personnel decisions such as drafts and trades, although on the floor personnel decisions obviously counts.)

If you have a scrub team, like the Brooklyn Nets, even Pops isn't going to make them better. On the other hand, any mediocre or even bottom level coach can coach the LBJ-led Miami heat to championships. (And let's face it Spoelstra is basically your median-level coach, not crap but not great, right in the middle IMHO.)

If I had to rank it, I would say I would rank (from matters most to least):
1. American Football
2. Soccer
3. Hockey
4. Basketball
5. Baseball

Due to the complexity of the game, I think American Football Head Coach matters the most. I think that MLB head manager matters the least and is vastly overrated. The difference between the best, median and worst MLB manager is probably negligible. I think basketball is somewhere in the middle compared to the other team sports.

What do others think? (Obviously few of us are fans of all five sports so just rank the ones you are familiar with. Or just talk basketball if that's all you know.)
