Those are the bad calls that happen to everyone.
Bad DPI call, that happens to everyone.
The gutless, lets let the ball carrier fight for yards, unless he fumbles then blow the whistle and say forward progress stop, has nothing to do with the Tush Push. Officials have been doing that forever. I have no idea why it happens.
If they going to let the pile get pushed, and let the ball carrier fight for yardage, which I'm in favor of, then when that ball carrier gets stripped, they should call it a fumble.
But these gutless, inept jellyfish officials immediately, if they see a fumble, blow their whistle and call forward progress stopped. I dunno why. Someone should ask them
