I think it's
all about minimizing mistakes. Tackling, blocking assignments, dropped passes, penalties, kicks, bad snaps. I agree so much that more games are lost rather than won in the NFL. When the Rams don't have a ton of mistakes they can compete with any team in this league- and I mean any.
I still believe the Patriots don't win because they make more big plays than their opponents- they win because they make far fewer mistakes. Last night vs. ARZ was a good example.
Play smart and disciplined.
