Look at Buffalo yesterday. Jay Feely kicks a 61 yd FG to tie the game then misses a mid-30 yd FG that would've won the game. Arizona could be 5-1.
Cincinnati had a chance to win the game on their final drive vs. Miami but didn't. The Dolphins had a chance to beat the Jets with a FG on the last play of the game and they failed. They also failed to stop Kevin Kolb on one final 4th and 10 play which is successful, the game would've been won.
At best yesterday the Rams make the game-tying FG at the end of the game. What happens after that is anyone's guess.
