There’s a lot of tradition with a franchise as rich and as experienced as the Dallas Cowboys.
There are reasons things are done, a way of doing those things, and an expectation of results for those things and reasons.
One of the more longstanding traditions is one people take a bit of issue with, it’s part of the Cowboys uniform. Dallas wears their traditional white jerseys more often than any NFL team wears any other, and when they go white on top they go silver on bottom... kind of.
Back in the days before HD television, the Cowboys did wear silver pants, at least that’s what people saw.
