In The Ravens/Browns game, the real refs got it as wrong as the other guys did in Seattle. The Browns should not have had their last offensive play after the penalty.
Fourth-and-8 on B12. A legal forward pass is incomplete behind the goal line. After the incompletion:
a) B1 knocks A1 to the ground.
Ruling: Enforce from the succeeding spot (B12) as the pass was incomplete in the end zone on fourth down.
B's ball first-and-10 on B6.
The second hail-Mary should not have been allowed. If the Browns would have tied and won that game it would have been an even greater error by the refs as this error was completely about KNOWING the rules as opposed to interpreting the actions of the players.
