Why so much coverage of him?
Jones is outspoken and puts himself in the limelight far more than other owners .
He gives interviews far more than probably all the other owners do so is the most recognized and fans have a love/hate relationship with his team.and him
Networks use that to make their coverage of Cowboy more interesting on the personal level
of how the NFL fans see the game and make sure they see the man that is loved/hated by viewers gets a lot of airtime because of the fans interest in him.
Many owners much rather shun the limelight, Jones just about demands it be shined on him and the networks oblige.
Others in the mist of problems try not to be seen and probably let that be known.
Jones relishes talking about problems his team and him are involved in and makes sure his POV is put out by him, not his spokesperson.
Networks know he's part of the attraction to cowboys by football fans and make sure his recations during the game is made part of game coverage
