Futsal Is Superior To Walled Soccer In Terms Of Developing Better Skills And Techniques. In Traditional American Walled Soccer, Players Regularly Whack The Ball (And Sometimes Their Bodies) Against The Boards, Which Promotes Improper Technique And Too Often Rewards Errant Play. Additionally, Players Usually Do Not Have To Work As Hard Off The Ball In Indoor Soccer Because A Player Can Use The Wall To Work A Pass Into A Guarded Teammate. In Futsal, Players Are Constantly Reminded To Play The Same Quality Control Game That Is Required For Success In The Outdoor Game.
