To start with it HAS to be in DC.
I wouldn't mind a retractable roof type stadium, but an overhang of some sort is essential. I know it's RFKish to say that, but the truth is, part of the reason RFK was one of the hardest places for opposing teams to play was because crowd noise was out of control....& a huge part of that was because of that overhang, So, either an enclosed stadium or semi-enclosed to keep the noise level optimized.
Fewer seats. Where are we now? Like 90,000+? Drop it down to about 70,000 or so.
I know this won't be received well by everyone, but set up statues around the outside of the stadium in strategic areas, at gates where people enter the stadium. Goerge Preston Marshall, Jack Kent Cooke, Joe Gibbs, George Allen, John Riggins, Sammy Baugh, Sonny Jurgenson, Art Monk, Darrell Green, & of course, Sean Taylor. Maybe some other players I'm missing at the moment.
I would like to see a much more Redskins fan friendly environment, rather than an NFL fan friendly environment. Something that expresses the general dislike for Dallas, Philly, & NY especially, since they're in our Division, but also something that tells opposing team fans, "You're in OUR House!" I'm not exactly sure what, without it being politically incorrect.
I would like to see it named for the team, not some corporation that sponsered the stadium. Redskins Stadium, Redskins Nation, or Redskins Park. Anything that indicates "Home of the Washington Redskins".

What Snyder did do tho was sponser the stadium thru FedEx, renaming it & trying to improve it throughout the years with many renovations. Some that haven't gone well, some that have.
