Don't understand why every team has to add a black jersey when black is not part of the team colors. Do middle aged team execs think it looks 'cool' for the kids. It doesn't. And it doesn't look 'tough'. Maybe it's a holdover from the 80's when teams switched from bright colors to black - like the Kings and a lot of prominent hip hop stars wore white sox, and raiders stuff.
The 2 teams who do wear black at home - The Raiders and Steelers haven't been good in a while.
