The Steelers will be at home...again! The Ravens on the road...again!
A Superbowl winning QB vs a rookie.
"Fast" Willie Parker stands a better chance of breaking a few long runs.
Hines Ward will be the best receiver on the field
The Steelers not only have the number I ranked defense, they have the leagues defensive player of the year

Just too much for the Ravens to deal with, so they won't.
