So the pass interference was legitimate and that holding call was legitimate?
The pass interference call was legitimate. The holding call did NOT result in addition or removal of any points (that was Seattle's fault).
Yes, they both were legit calls. Tough for Seattle for sure but don't do the crime if you can't do the time.
Just your opinion. On the interference call, if the D-back had pushed exactly the way the receiver pushed, and made the interception in the end zone, should a flag have been thrown?
