Like the person above said, you can't see how good, or not so good he is in a few games.
Plus, you may be showing some bias towards Benzema there, because if you#ve "read a hell of a lot of intelligent articles about him", then no wonder you're under the influence that he's so good. Any writer of some sort can make a play sound good, and overexaggerate there abilities.
Benzema's good, but he's no where near as good as everyone seems to make out.
