It's a common narrative that all a baseball manager can do to affect the outcome of the game is set the lineup, manage the bullpen and decide when to pinch run and hit. I am sure there is behind the scenes value the manager can create or destroy but baseball seems to be the team sport where in game coaching is least important. On the other hand coaching (especially play calling) seem extremely important in football. I think in game coaching can also be pretty important in basketball and hockey as well.
Shill me the sport(s) you think coaches (managers) can most impact the result of the game.
Sats for all.
Cheers,
