This whole thing got me thinking. What if we combined two sports - basketball and ultimate fighting? You would keep the basics of basketball - getting the ball into the basket - but other than that, anything goes. Kick, punch, shove, chairs (like in pro wrestling), tackle, stomp on. It's every man for himself, just get the ball into the basket as best as you can. No more dribbling, just carry it and get there any way you can.
You talk about a spectator sport that would kill the NFL!!!
