I am not going to knock some of the posters here with their opinions but clearly some people have never worked in the game at any level and give opinions. So it's important not to read anything infantile and give it any credence. So let's stay on topic. This is a futsal discussion and it is relevant with indoor soccer, pro or amateur. 1. Futsal can be played indoor and/or outdoor, with goals or with cones or 2 poles or anything else you want as a target. For example, when I worked with urban youth, we played futsal on a basketball court all summer kicking to the post (as a goal) and they loved it so much, that hours after practice, they played their own futsal scrimmages until dark. All my urban players went on to play college soccer on scholarship. 3 are now outdoor pros. I am not saying that was because of futsal but it certainly helped them in their youth development. 2. Indoor soccer requires boards. This is not easily reproduced in any gyms unless you have a gym with walls where there is nothing impeding the rebound or ball roll on the sides. My suburban elite players used to play indoor soccer every Winter. Their combination play was excellent. But none developed the footwork that made them stand out on the pitch until I worked on dribbling every week and encouraged it in outdoor games and promoted it more in futsal in summer and winter. When we moved from indoor to futsal the difference was night and day and the teams they used to play in indoor (with their constant banging it long and looking for rebounds) were replaced with teams who had control of the ball, passed with accuracy and speed and enjoyed many 1v1 and 1v3 challenges. 3. The tricks are what makes a player special with the ball. Just who would you say is the best player in the world? Ronaldo or Beckham, Messi or Gudjonson, Ronaldinho or Pirlo, Robinho or Adriano, Kaka or Seedorf, Ibrahimovic or Trezeguet, Marta or Wambach? All the above are top notch players but what separates the best is their ability to do something extra with the ball. The tricks. Futsal promotes the tricks in YOUTH players and they bring that to the outdoor game. That lack of fear, that total confidence that enables them to go beyond the average "collect and pass" style soccer, that promotes real skill and ball mastery. Working in youth development, I am only interested in doing things that promote the skill in the game. That could be anything from traditional soccer squash (banging the ball off a wall with a teammate) to develop shooting power and accuracy to street soccer to bring out individual creativity without fear of consequences. But when they go from the practice environment, I want players (of any age) to still play with the freedom and self expression of their personalities. Then the game is enjoyable to watch. There are already too many "anti-soccer" coaches out there that kill all the fun and skill out of players and focus only on team results...Peter Nowak at DC United was one who killed America's greatest talent in Freddy Adu. People like that who put their own ego ahead of the player's character do not belong in the sport. So with America being so big, there needs to be a thread that ties the nation together in skill development. A culture. Outdoor soccer with the endless calender of tournaments is not the way (and I've done all the major ones for years). Indoor soccer with it's Winter only playing off the boards is not the way (fun but too limited). Futsal with it's easy access indoor or out could be the way. We have to at least give it a generational chance to succeed.
