It would be great to get rid of the challenge brick, or if necessary, limit review time. I understand the importance of getting the right call made, but it's a killer as it is right now.
Also, I understand it's Real American Freestyle, but it'd be cool to mix in some foreign stars. Additionally, the market in some of these countries for PPV or whatever is massive. Money talks, both to get the foreign wrestlers and the international audience.
Finally, to appeal to a broad audience (other than folks on here, who would watch anyway regardless), I think you have to have storylines. Casual fans need to feel connected and invested in the wrestlers, and if RAF believes in their mission statement (on their website) to, "create a platform for elite athletes to compete in front of millions of fans," that doesn't happen is a peripheral sport like wrestling unless there are storylines.
