You're right it's not acceptable. Yet... it's true. Look how the defense played after halftime when they got laid into at halftime. They dominated until their frustrations boiled over (also unacceptable...) late from the offense's inability to do literally anything.
Fact is the Rams have the talent to play with just about anyone when their heads are on straight. I hope they are this week. A great 60-minute effort at home.
Again not excusing it. It's been a pattern of Fisher's Rams teams for 4+ years. They dial it up and down inconsistently. Let's hope it's up this Sunday and it installs some confidence going foreword.
