Goodell did not set a course in policies that divided fans over political issues.Kap started it and Goodell had to deal with it.Your solution would not have the approval of 85 % of fans including myself, millions of minorities and millions of white liberals. Forcing Black players to stand because Trump and racist whites say so would cause bigger problems than they have now.The media,minorities and civil rights organizations and leaders would brand The NFL a racist organization and that would stick with the league for decades.
If the boss cannot deal with actions of employees who hurt the league and take effective action to resolve this issue -- then Goodell is not fit to be the boss.
