Both Mannings are buttholes. I've seen John Pagano's defenses for years come out in the second half of games and completely shut down offenses That was his role with Wade Phillips who had him in the booth charting the offense and game planning the second half. This is why when Phillips became HC in Houston he tried to take Pagano with him but was denied.
This came out during an interview with JR Seau who talked about the differences between the 3-4 hybrid vs a standard 3-4 and 4-3 scheme. The hybrid scheme (the scheme the current Rams were built to run) gives the DC the extra flexibility to make those adjustments. The same can be said about offenses. The Mannings either don't know or they are lying.
Hell, even good college teams do the same thing. How many times have you seen teams get stoned in the first half and then explode in the second, either offensively or on defense? This is the difference a good coaching staff makes. This is also why teams have migrated to the 3-4 hybrid, i.e. sometimes called 4i scheme. It's why I keep saying that Morris isn't using his personnel properly. Morris is strictly a 4-3 scheme guy and plays this roster that way. It's why he took a #1 ranked defense and tanked it in two years to an 18th ranked unit.
