The game thread 2 days ago had some decent uniform discussion with some interesting concepts. With Jim Crane imminently taking over, you have to think he will put his own touch on the uniforms to signify a new era in Astros baseball.
I'll go ahead and get my personal opinion out of the way. I'm a traditionalist, so I want the colors switched back to Navy and Orange. I think they should go with a modernized version of these:
Lose the pin stripes. Lose the Brick Red and Gold. Go back to what started it and stick with it.
