You simply cant fire everyone after a few yrs especially when there record improves every year except one bad/off season. In the NFL you have to have Continuity to be successful and that's the bottom line. Did The packers Fire Mcarthy after a 6-10 season? NO they did not! That was following a NFC title game appearance year. Schwartz has done more good than bad.
If we're talking about continuity regarding the tenure of Coach Schwartz, then the 10-6 season was the ONE year not following a trend. That one's the anomaly, and this year is more in line with a pattern.
