Watched the Steeler replay on the NFL Network Wednesday

Did Copper cost us the game? No
Did Copper cost us a chance to tie and possibly win the game? Yes
There is a big difference in the 2 questions.

No 1 play wins or loses a game. It's a combination of every play in the game. I thought the young man played well. The dropped ball was really a nice play by the db. The fumble was also a nice play by the db. I guess it's simply how you want to look at any given play or game.
