I think so....

Reading McVay's comments it 'seemed' to me that a lot of the problems with the OL last night was missed assignments.

Obviously this could all turn out to be the 'worst'... but I'm not there yet, or even close. When an entire team except for what? 2 players? Play that poorly I HAVE to believe the main culprit was poor preparation.... which could have been caused by many factors.... ego among them.
