Michael Brockers helps an improving Rams defense

Officials are so vigilant about protecting the quarterback, Michael Brockers made a textbook hit - and still got flagged.

St. Louis Rams coach Jeff Fisher praised his defensive tackle right after a 42-21 victory over the Chicago Bears on Sunday, and the next day, too.

Fisher thought Brockers was penalized because the hit was so good.

Going forward, he wouldn't have the Rams' first-round pick in 2012 change a thing. Brockers has been a force in the middle with 3 Ã?½ sacks for the Rams (5-6), who play at San Francisco (6-4) this week.

Brockers was called for roughing the passer after bulling up the middle and leveling Josh McCown in the second half.

Referee Jerome Boger said it's the correct call because the defender led with his helmet into the quarterback's body.
