If Ross wants an attraction for the stadium....... then why not just build an NFL MIAMI DOLPHIN EXPERIENCE theme gaming area? Have it open before and after the games, and charge an entrance fee, and you could even include "package pricing" for Sunday's game + entrance to the gaming area type of deals. The games in there could be all about football.
So......example.. a QB CHALLENGE area filled with the following :
QB ACCURACY - where fans get to throw accurate passes into life-size Dolphin player cutouts, and it shows up on a little scoreboard there.
QB ARM STRENGTH - add a speedometer type of thing like they use in baseball, and fans can see how hard they can throw a football, and they have to hit a target
LINEMAN CHALLENGE - where fans have to get in a 3point stance and explode into a soft bag and it records how strong you pushed it on the scoreboard
lots of games like that, using all DOLPHINS players cutouts. Add in carnival like scores to win Dolphins gear like T-Shirts, plush dolphin stuffed animal, Dolphins hats, etc....
Then, add a "Meet a Dolphin" area, where every week, 1 Miami Dolphin player on the current roster is there to take pictures with the fans for 30 minutes. You could also add a bunch of other cool little things that are cheap to maintain and introduce.
