They know before the season starts which uniforms they are going to wear each week so everything is pre-determined, and authorized, with the league. My concern is that the NFL seems to getting pretty lenient with the socks. Players seem to be wearing whatever they want. Both teams wore white pants with white socks on Saturday. If the Cowboys had been wearing their blue socks, they probably would not have been penalized for that BS tripping penalty with two minutes to go. Without that penalty, Pollard is close to a first down which would ultimately allow the Cowboys to run out the clock. Detroit doesn't get the ball back, Detroit doesn't score, and no 2-point conversion garbage.
