when you look at stats:
http://www.nfl.com/gamecenter/201101...fs#tab:analyze
the only significant difference are:
Chiefs run offense - way better than the Ravens
Ravens run defense - 93 yards per game
and points allowed:
Ravens - 16.9
Chiefs - 20.4
3.5 points is huge in the nfl
Flacco and Cassel are almost mirrors statistically, with the main difference being accuracy:
Flacco - 62%
Cassel - 58%
but their ratings are basically the same
it really comes down to can we get Charles loose against their front 7....and then will Casasel or Flacco not crap their pants....
