One of the primary problems with college soccer is the lack of actual coaching that takes place. Don't get me wrong, coaches attempt to coach but they often mistake a competitive environment for actual coaching. What does this mean? This means that coaches confuse the natural progression that occurs when athletes practice and compete with other high level athletes, with their ability to coach.
If you're a coach reading this, the question is: Are your players improving because of your coaching, or are they improving simply because they're playing with better players?
If the answer is the latter rather than the former then you may be contributing to the problem of college soccer.
There is nothing wrong with that type of improvement, but that's the kind of improvement that plateaus after a year or two. That's the kind of improvement you see when a freshman enters a college environment with better athletes and older players. Naturally, the player will improve but after a year or so, with the adjustment period accounted for, the player plateaus because the coach is no longer developing the player, and never was to begin with.
There's no problem with improving simply from playing with better players but that's the kind of improvement that stops after a while, leaving both players and coaches frustrated.
