Every outdoor or indoor games success may be depend on the infrastructure of the game. At least i think. Because if you have not perfect infrastructure you can not practice properly . Am i wright ? Though success depends on practice so you should build infrastructure more more and more. USA's infrastructural condition in the world is best all know this. That's why they are so good i think they are unbeatable in basebal.
All together is necessary for success. First players then coaches and conditions for practice...
