Yeah, I can't picture that being the best look.
But green pants would look great with the black jersey and green helmet. Green, black, green. I imagine that looking even better than the all black unis with a green helmet. I do hope they don't go with black jerseys for all the games though. I would like to see 1 game with black jerseys/black pants and a second with black jerseys/green pants. Otherwise use the traditional green jerseys.
