honor your past while keeping up with the modern era. The orange helmets have GOT to go, obviously. And some sort of symbol is needed, even if it's just the letter 'B'. I really like the first picture and I think Browns fans could get on board with it as well. While playing Madden I created a Browns look featuring a bulldog with colors and symbols much like the third picture, but I think this is perhaps too deviant from the current standard.
Whichever way you want to do it, I think it's past time to make some waves. Change your uniforms, change your colors, change your attitude, but change something so that the improvements you've made in the off-season don't go to waste.
