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).
Apparently, you missed the Carolina game. Carolina was hot as a pepper coming in. They got utterly destroyed. (As did Denver, I'll concede)
