We've had a great run with helmets but that concept is one of the WORST I have ever seen.
Right now, our current uniform set is one of the best in the NFL. It's so classic and looks so great color- and design-wise that it should not be touched. If we do change, I vote for the return of the spear or the Lombardi set, both are great, but our current ones are the best and there is no reason to change or even tweak them.
Wearing white-on-white should be banned though, I hate the look.
