There is no perfect NFL owner so I will construct one using bits and pieces from select owners.
1. Tenacity - The Rooney's, Pittsburgh - Every year you can count on the Pittsburgh Steelers to be tough as a two dollar steak. In a lot of ways a football team is a direct reflection of it's owner.
2. Patience - The Rooney's, Pittsburgh - Has anyone ever seen the Steelers go on a free agent spending spree? Yet they are always competitive because they keep it simple.

3.
Football IQ - AL Davis, Oakland - Say what you will about Crazy Al now, but Al Davis has forgotten more football than most of these current owners know. Al Davis is responsible for a good portion of the modern day game we see today.

4.
Business IQ - Dan Snyder, Washington - Say what you will about his decision making and patience but ever since Snyder took over the Redskins they have been a money making machine especially for a team that does not win on the regular. Honorable mentions are Robert Kraft and Jerry Jones.

5.
Community Sentiment - Ralph Wilson, Buffalo - This guy is absolutely beloved in Buffalo. I am not saying other cities don't love their owners but I've been to many NFL cities and Buffalo's relationship with Wilson is a notch above IMO.

6.
Innovative Thinking - Community Ownership, Green Bay - Gotta love it that Title-town USA is owned by "We the people". Now that is a concept that I would like to see more of in sports.
