The NFL has a major problem with its new emphasis on roughing the passer penalties.
Roughing the Passer calls are absolutely out of control.
The league has become famous for lurching from controversy to controversy, some beyond its control, most through it's own ineptitude and desire to try and solve small problems with ill-advised,sweeping rule changes.
The Tuck Rule, the absurd celebration penalties, what is or is not a catch. These were all issues that had easy fixes that the league took forever to rectify, but rectify them it did. At least eventually.
