Most real owners are idiots when it comes to hiring GMs and coaches. Look at the 49ers, Titans, Jacksonville, Chicago, Jets, Dolphins, Chargers, Redskins, Browns and Broncos.
The patient ones, Steelers, Giants, Eagles, Patriots get actual returns on their investments. Jerry's best teams in Dallas have come because he listened to others about the draft and kept one head coach and kept his meddling to below normal.
Unlike QB, there are 32 qualified candidates for NFL coaching gigs. The first questions are always what kid of front office do they have and what kind of talent on the field. The most important question is whether or not the team is patient while the coach improves and learns.
