KC had to reshuffle it's entire line because of an injury to Fisher in the Buffalo game. They weren't up to it. This is apples to oranges and has nothing to do with the state of the Rams O-line.
PFF season rankings had the Rams 2 spots ahead of the Bucs at #3. Of course we didn't have Tom Brady.
We need a more physical center, some more maturity and consistent play from Edwards and Corbett and we should still be pretty good. Whit and Havs both had solid seasons statistically - why blow that up?
After watching last nights game I think outside pass rush is our biggest need.
