The first half, the Bears would have beaten any team they have played all year if they'd kept it up all game. They executed so well early in the game and jumped off to an early lead. In the second half, the Bears looked terrible, and thank god we were playing the Rams because any other team would have came back in that game and made them play till the final second.
So to answer your question, the Rams are just that bad except it wouldn't have mattered in the 1st half because the way the Bears were playing they would have been ahead of anybody!
