I haven't read this entire thread, but I just don't know why a lot of you are leaving out the NFL relocation fee. Some reports peg that amount at about $600,000,000.
If that is true the simple math is that if you bought this team and wanted to move it tomorrow it is going to cost you fees in the neighborhood of one billion dollars (cue Dr. Evil with his pinky to his mouth).
Sure, that are a number of rich people on this planet, rich enough to pull that off. However, it just plain doesn't make any business sense.
EDIT: maddog69, my apologies, brother. I didn't make it to your post.
$900 million! Well that just makes me feel even better!
