To the OP's point. Is the question that the NFL is too invasive? Too personal? Are we shocked that we got too close for comfort or is this what the public craves?
It's sad, but the public does crave this XFL type show more now. I think more and more of it is all fake and choreographed than before, much like "viral" youtube vids, but that doesn't matter. People eat this dreck up. When it is sponteaneous like in the case of Richard Sherman, it feeds a whole new subset of the generation that glorifies the gangsta lifestyle. And it's not by chance, there's money in that demographic, if you include all the gangsta wannabees. the guys who wear the black shirts with the "You Mad Bro?" on the front. The NFL hasn't become the XFL. We became the XFL, and the NFL is just giving us what we want, or what the numbers say we want anyway.
XFL was ahead of its time. But it was bad football product. Pretty soon, the NFL as we knew it will be no more. We already gave the NFL too much latitude with what days/nights we would support football. Too much latitude allowing the game to inundate us with commercial break after commercial break so much that our only solace on Sunday is the RedZone channel. They drove a new product down our throats to escape from it. Now the NFL is getting us down on the field for candid moments at the end of games. And players are slipping into their XFL roles on cue, and the public eats it up as the ratings arrow pegs, and the NFL is quite happy about it. You've been played.
