.....generally speaking the kids with higher Soccer IQ understand angles, spacing, possession, timing of runs, they know when to delay and wait for help, box in opponents, have crosses like demons and are unselfish players. They play all the positions, even goalkeeper at the uLittle stage. If your kid hasn't been playing all the positions, then his soccer IQ will remain stunted.
The points made are very true, except the last statement. While the last sentence may be true at times, its one of those things that analytically sounds correct but not necessarily so in practice.
If the point is to say one needs to understand the game tactics and spacing for attacking and defending, in the context of overall strategy of the game, then fine. We agree completely. But its not necessary to play every position to learn and know the concepts and tactics being employed. Excellent players know all the intricacy that the position brings that he/she plays. At the higher levels, each position has its own specialist, as it were. In other words, its a age old question of is it better being a specialist or generalist.
..........When a College coach asks here what position she plays, she needs to answer "Whatever position you need me to play." Right now, she only understands striker. We still have a few years to develop her into a complete soccer player. I'm going to have her play in the back and when she has mastered that she is going to be moved to mid.....
This approach is fine when the player is younger but as he/she matures into older, need to really develop instinctual knowledge of how to play the primary position. All the subtleties that any position brings need to be an automatic reaction/muscle memory and not something that has to be thought of, since the game is significantly faster at a competitive levels.
The cliche really fits (jack of all trades, master at none) because all around good player can be a utility player that can fill the void at times but not likely to be the featured player. While all excellent players are good overall players, they excel at one or two positions. And to be excellent at one or two positions, they don't get there by playing every position.
I'm not arguing for the sake of arguing or disagreeing these points. Rather, sharing a different and counter intuitive perspective because there's a real danger of compromising a real quality players into a role that makes no sense for the sake of "development" by conventional wisdom. Just need to evaluate and make decisions based on who the player is.
