recognize large patterns of dysfunction when things aren't right. Coaches know way more about football than fans do but they aren't competing with fans. They are competing against other coaches and teams and the results say they aren't cutting it.
Some people think fans should only say positive things and support the team 100% of the time and that is pure fantasy. The coaches and players get the upside and downside of fame. Fans should focus their criticism on the on-field results and leave personal lives out of it.
