I think mound visits, and certainly the quantity of them, are part of the problem but, yeah, baseball is hardly alone in this area. Football and Basketball have at least as many breaks and whether the game stops when the manager goes on the field to meet the players or when the players walk off the field/court to go meet the coach is a distinction without a difference IMO. There are simply too many time outs in American sports. Soccer get it right here. Strategy discussions are for pre-game, for half-time, for practice time. More responsibility should remain with the players to make decisions on their own.
