LMFAO at Miami having any bag game. There's not only a problem with keeping it a secret(This is Miami, not some jerkwater town in the middle of nowhere), you also have to deal with having legitimate media sniffing around. It's not an accident that Miami, SMU, and USC have all dealt with major scandals over the last 30+ years, while schools like Alabama have done far more, and gotten relatively light punishments. It's because being in a major city limits what you can and can't do in regards to ethically questionable stuff.
There's a reason why schools like Bama, UF and others don't want student athletes to get paid above the table. They know that in a truly capitalist system, schools like Miami could compete in that system, even though Miami wouldn't be able to offer an obnoxious salary. Living in Miami, and making a little scratch is better than being paid like a king, but living in Tuscaloosa.
