I somehow agree with most of the comments above, but in my opinion, it is not that black & white. My bb is a goalie and he has been fulltime since he was 8. It depends on so many things, but in our case, he had an extraordinary Keeper's Coach during U8 and U9 who quickly identified his potential and most important, his interest in the position over every other one. This Coach explained to me that even though it is great having the field playing experience to apply when a player becomes a fulltime keeper, it is not essential to be a good one; and on the other hand, the earliest a goalkeeper learns (remember, repetition, repetition...) the techniques, systems, strategies and develops the natural skills, a greater advantage will have later on, over strikers and even other goalies.
Don't get me wrong, my son's personal record juggling the ball is 150-ish, he knows more tricks with the ball than most of his teammates and utilizes his "other" foot when required.
You might know that there are tens of techniques and methods, for most moves a goalie performs during game-play. Timely positioning, precise tempo coming out (at what exact moment to dive for the ball during a One-on-One play), optimum point (of the ball’s curve) where to field the ball on a cross, most efficient landing method (not diving, landing…… but diving, too) for a quicker reaction on a rebound, when to use which hand/arm, when to use the palms, closed fist, proper foot-work for more efficient displacement inside the Penalty Box or Goal Box (yes, there are specific techniques for each) and so forth…. You can only learn these things practicing (to create the habit) and through game-play experience; so if you start at 14, you could miss substantial instruction and could have to fight “vices” you might have developed over time.
Then again, this is my experience with my son and my godson (who reached a 3rd string Pro level a few years ago). You will have to evaluate your specific situation, I guess.
