In the Redskins game... the booth claims that it's totally ok for the offensive player to grab the back of the jersey and pull the defender backwards away from the runner he is attempting to tackle. They claim that is NOT holding.
Proof of their assigned role of damage control department for the league. Fuck off... everyone clearly saw it as the reason the bear QB was able to score a TD... so they tell the entire viewing audience that what they just saw with their eyes in the replay was completely legal.
Just wow.
