If you don’t have an above average quarterback in the NFL, your odds of winning anything are significantly hampered.
This isn’t the 1980s.
Hell, this isn’t even the early 2000s. The chances of seeing another Trent Dilfer led Super Bowl champion are slim to none in this era of the NFL. Every new rule implemented in the last decade has benefitted the offense. The NFL wants exciting games with splashy plays, and a 13 to 10 defensive struggle isn’t their idea of sexy.
Tackle the quarterback too hard, that’s a flag. Land on the quarterback after a tackle, that’s a flag.
