No luck required. The hawks have a better QB, a better RB, a better offensive line, and an equally impressive D.
The two week max-out-the-hype interval between the conference championships and the Super Bowl will probably play its usual havoc with timing and intensity and that affects both teams. But honestly, if the Steelers play like they have been for the past few weeks your Seahawks will be running into a buzz saw (IMHO, of course).
