Matt Hasselbeck, long time game manager, is the great QB that led the Seahawks to the SB in 2006? Really? Everyone knows that offense started and ended with Shaun Alexander.
Hey, Mark Rypien isn't a great QB but the year he went to the SB he was great. Nothing says you have to be consistently good just good for a year and he was. Again, great QB play + great defense = success. Always has, the run game doesn't matter. When Hasselbeck and that D slipped SEA vanished.
Put another way the NFL strips away the PIT D, HOU D, SF D, Drew Brees, Aaron Rodgers, Tom Brady and Ray Rice from their teams is there anyone in their right mind who doesn't take all the D's and QB's before the RB if they are not playing FFL.
