i've always wondered about this and nobody can seem to give me a straight answer. why is it that in college hockey, the ohl, the qmjhl, and highschool hockey all those goaile wear the different type of cage on their goalie mask, but as soon as they turn pro they change it to the style that all the nhl goalies use. is that type of cage not allowed until you become a professional. Any feedback on this topic would be greatly appreciated.
