I can't answer that. IF he wasn't ready, why would he be out there. He had to use his weapons to take the focus off of Alexander. Has JS caught those balls, Alexander would've gone for 125 in the game. Hbeck tried to go to everyone and he used his own legs on occasion with effectiveness. Hasselbeck was ready for prime time in my opinion. Couple of bad tosses, but that can be expected against that defense and during the big one. Seattle made Pittsburgh's defense look average....soemthing high powered Indy, Denver and Cinci could not do. Great game by Seattle,...ball did not bounce there way.
Yeah, the breaks and big plays went the Steeler's way and that really told the tale of the game. Seahawks had a bunch of momentum killers (missed field goals, flags at the absolute wrong moment, dropped balls), and they didn't really try anything on offense to break that sense of swimming upstream. The Steelers had their end-around, bootleg passes and halfback passes to create big plays -- the Seahawks continued to play it pretty close to the vest even when the game was in a bad pattern for them.
The Hawks had a team speed advantage, but never capitalized on it and never really tried to do anything out of the ordinary -- which given the outcome and with hindsight I'd have liked to see them try something out of character to break the game's pattern.
