I mean to be frank, Urban can really demand whatever he wants as he is living a pretty cush lifestyle as it is. And in the NFL, you can employ abusers and drug users without anyone batting an eye so he'll probably be ok
If I were Urban, I would demand the moon and the stars as well. He's a very, very valuable commodity, value may possibly never be higher, and he doesn't NEED the gig. I couldn't imagine being in a stronger position of leverage than he is at the moment. The Raiders gave Gruden $100M for 10 years.
To go to one of these grease fire franchises, I would take everything you can get from them. Bend them over and give it to them straight up the tailpipe. I hope he gets his, good for him.
