Absolutely. I let a little more go uniform wise at the lower levels because they are a little younger. I don't expect a freshman in high school to have different colored undershirts and such. I guess I view the lower level games as more of a learning environment. I always inform coaches and the players about the uniform violations, but more often than not I let them in the game. Of course this is the total opposite of my view on sportsmanship where I take very little unsportsmanlike behavior from lower level players and coaches. Maybe I need to work on my own consistancy
