They both have a huge ego and pride, and don't want to seem to share any credit for the teams success with their coaches, management, and they would rather lose their way than win someone else's way.

However, at least the Cowboys have made the playoffs in Jerry Jones's elderly years, the Raiders would never sniff the playoffs again in Al Davis's last decade as the boss, and they had very few playoff appearanes in the last 26 years of his ownership of the Raiders.

The Cowboys however, have won only 4 playoff games since that 1995 Super Bowl victory season i think.

Just brining this up, because i believe Jerry Jones and the late Al Davis, were often compared to each other, in being hands-on NFL owners, bosses, that micromanage everything and have a huge ego, refuse to hire a GM.
