2nd jersey should be the reverse of the home jersey colours - blue with white numbers. Same pants should be worn with both jerseys.
When I hear the complaints about the green pants I think we're lucky. Imagine being a fan off:
Browns - this year's uniform is the worst ever.
Bucs - don't look like a NFL team - too gimmicky.
Gnats - they wear grey pants because in the old days detergents weren't as good so whites went grey after a couple of uses. What next? Grass stained jerseys?
Skins - yellow pants make them look like a 70s high school team.
