The fact is that Jimmy has no more success without Jerry than Jerry does without Jimmy.
This is true based on each individual's degree of commitment. Let's review:
Jimmy Johnson
NFL head coach: 1989-1993
Out of the league: 1994-1995
NFL head coach: 1996-1999
Out of the league: 2000-present
Jerry Jones
1989-present
9 years versus 34 years.
Shouldn't the guy, with 26 more years in the league, have created
much more success demonstratively over the guy, who has been out of the league completely for nearly a quarter century? Not counting his time fishing between his head coaching stints in Dallas and Miami?
