I'd revamp the current concept, but just make it slightly more modern. Maybe darken the burgundy some, touch up the stripes you want on the pants/sleeves, etc. Do soemthing to make everything consistent regardless of which combinations they wear.
I love the Indian head logo...it brings me back to the 1980s and my youth watching championship teams. Not liking it would be akin to thinking Santa Claus is too fat, in my opinion. So, keep it, but just clean it up. Go with:
Burgundy/Gold at home
White/Burgundy on the road
Have both versions of the throwbacks (I love last year's but could also deal with the spear helmet versions) so that you can wear those either at home (burgundy) or on the road (white) during Thanksgiving weekend.
Done.
