This has been true for a minute but this is an indictment on the coaching staff. Some coaches can see what you are doing to them at halftime, make an adjustment and see if you can do the same. Heck some don't wait until halftime. The Rams however have been played the same way for years now (at least two) but the Rams haven't adjusted accordingly. If the opposing team is going to get rid of the ball fast then play their receivers tight by the time they shake free the qb is sacked. So the thing that the great coaches can do after two or so drives the Rams can't do in two or so years?
