Are you making an assumption that we wouldn't play any other games at Hard Rock, because I was thinking if we ever got some type of on campus/close to campus stadium, we would just use that stadium for opponents with lesser appeal or off-years for Miami, but if there were marquee games or years in which we were doing well, we would still use Hard Rock for those games. We either have big time games, or we have games in which most of the time 55k would fill up the stadium completely.
I also think this is all an uphill climb, but I do think some of the traffic issues that have been discussed also gets solved as a far larger percentage of students and alumni would attend if it's within walking distance from campus, as I would always park in and around campus/metrorail when I would fly in for games at the Orange Bowl. Honestly, this may take a lot of turns and may end up at a totally different location, but I'm just glad the discussion is taking place and with people who have lots of resources and connections.
