It was Wallace and not Hasselbeck who led the Seahawks' previously anemic offense on two straight game-opening touchdown drives against the New England Patriots last week, the first time the Seahawks have accomplished that this season.
Earlier in the year, when Hasselbeck was sidelined with a back injury, Wallace struggled to maintain any semblance of continuity with the offense. It was so bad at one point that coach Mike Holmgren felt the need to dial back the offense and call a more conservative game plan.
Turns out, Wallace was not 100 percent.
He had injured a calf muscle when the team was trying him out at wide receiver, which was necessary because the receiving corps was so depleted by injuries.
Then he suffered a groin pull, which prevented him from utilizing his best asset -- his mobility.
Wallace had it back last week, and befuddled a Patriots defense that got near him but could not catch him, something about which Patriots coach Bill Belichick groused after the game.
"I think he had a good game," Holmgren said. "He graded out very, very high. He threw the ball well, he ran the ball the way that we believe he can run the ball when he has to. He was healthy. And he played the game pretty confidently, I thought. I thought he was going right along. I'm hopeful, if Matt cannot play, that Sen can finish the year strong, and continue to play the way he played last week."
Wallace not only led the Seahawks in rushing last week, picking up 47 yards on three carries, but he also completed 20 of 28 passes for 212 yards and three touchdowns, piecing together a 128.9 passer rating.
It is the reason that Holmgren feels relatively confident against the Rams this week even though Hasselbeck is not playing.
"It's all about playing with confidence and having fun," Wallace said. "It's a team effort. We all went out and played hard on Sunday."
