How DonoShan will take us to the Playoffs this year.

[SirClintonPortis]

Quarterbacks provide a lot of utility to the team. That doesn't mean they can turn water into wine. But laymen love the "he's like Jesus" metaphor, no matter how silly it is.
Super Bowl teams have players who can make enough plays from to win it all. Where it comes from, it depends. There is not enough playmakers to go be so certain of a playoff run this year. A transitioning defense means growing pains as they learn it, which means plays that hurt the team. An unproven O-line coach and unproven O-linemen means that we don't know how much of a foundation McNabb has to stand on.
I believe that Shanny+McNabb is going to be an excellent combo, but they aren't going to be miracle workers.
