the patriots and broncos might be about right if it was their previous helmets. actually liked the patriot hiking the football. i think the browns, lions and packers should be higher. the packers is simply iconic.
i do like the raiders helmet. as a homer, i'd go with the current rams helmet as #1 but not bothered that only 1 other helmet was ranked above.
but if we're putting up the blue helmet with the white horns against any other nfl teams helmet from any era, there is no discussion, there is only 1 correct answer. and it's by a wide margin.
