Glazer nails it. He was in camp over the summer and he said you could see that on pass plays the receivers were taking too long to figure out what they were supposed to do. You could just see the team was struggling to play this offense. He said the Rams were hurt by the lockout more than anyone--ie, the combination of the lockout with THIS offense hurt them. Then he directly says, as soon as they started to get it together with the offense, they got crushed by injuries (though defensive injuries started before that).
Glazer adds himself to the list of people stating that Spags is viewed throughout the league as a good coach and that he will end up as a head coach again some day.
