This article is regarding Tampa Bay, but the same would apply to the classic Hawks unis. Basically, due to NFL rules we cannot change helmets, aside from decals, so we wouldn't be able to wear a silver helmet. Personally, I'm okay with this for 2 reasons: 1. I totally dig the new uni's. A throwback sounds cool, but it's not exactly like I'm sick of our look or anything. 2. I don't want to see a throwback uni until we hoist a Lombardi or two. Right now, this team is all about the future, and not the past.
