Apparently people actually read these, so it's long overdue for a new one!
We have different coaches at IGA, with varied backgrounds and coaching styles. What one coach says may be different to what another says... this can be confusing for young goalkeepers. Does that mean one of the coaches is wrong?
To answer this, think about Man City. Their last two keepers, Bravo and Hart, are completely different in terms of playing style. Clearly as young goalkeepers, their training had different focuses. Does that mean one is good and one is bad? Absolutely not, they both have their own strengths and weaknesses.
Take a basic technique, such as punting the ball. Some coaches are set that the drop kick is the only option to use (I can't get on board with this, personally). Others promote the sidewinder kick, and others believe in more of a straight-on, American football style punt. Different styles tend to work better for different players based on gender, physique and so on. The more techniques you are coached on and try, the more chance you have to find the best fit for you.
At the end of the day, if you a/ keep the ball out of the net and b/ can get the ball to your team mates... you're probably doing it right.
