I didnt say it was common but it happens, especially depending on the varsity team, why have some who wont see much playing time on varsity just ride the bench when they can start JV
where I live its common to have the backup varsity players start on JV to improve their skills and get real life action
AND THATS my point. why SIT on a Varsity bench just to say "see me, i'm wearing a varsity jersey, i hang with the varsity team" but you gets NO time. barely garbage time. 2 people have to go down at your same position for the coach to even look your way. technically speaking you're not at varsity level ability wise. you're there as a just in case situation. nothing more.everything less.
