Let me begin by saying: HAHAHAHAHAHAHAHAHAHAHAHAHAHA!!!!!!!!!!!
Stop. You're not going to compete with the NFL. Take it from Trump. And from the lameasses responsible for the XFL, that infusing your league a "rock n' roll image" only makes things gayer. Calling your team the "Hitmen" isn't "edgy."
If you really want to spice things up, give players medieval weapons. Imagine a guy highstepping toward the endzone, then suddenly getting a mace (spiked ball and chain) to the throat. Make Don Imus and some other loser shock jocks broadcasters, and make the NRA and Global Warming your sponsors.
These are the keys to success.
