I loved the Orange jerseys for the Flyers, and was really pissed when they retired it and made the Black jerseys the official home ones. Now the orange ones are back and will be worn every home game, save for some games that they will wear black as alternates. That's the way it was originally going to be, and now that the black jersey isn't going to be worn almost every home game, I'm OK with it.
I've thought for years the Phillies needed a red shirt for the uniform, but now almost every team who's got a red scheme, and teams who've changed their color scheme to red, have those. It would look weird now for the Phillies to do that and it would look like they're ripping off other teams. Their cream-colored thirds are eh..
Eagles' white jerseys are awesome. I wish they had a retro green jersey for their alternates instead of black.
