Marshawn Lynch could help passing game

Quarterback Matt Hasselbeck provided insight Wednesday into how newly acquired running back Marshawn Lynch might help the Seattle Seahawks' entire offense, not just its running game.

"I don’t know if we’ve ever had a guy like him," Hasselbeck told reporters, noting that T.J. Duckett was more of a short-yardage specialist than an every-down power back. "This makes it a lot tougher for people to defend us. It gives us a huge opportunity in play-action, it gives us huge opportunities with the naked bootleg and just all kinds of things."

The play-action reference was appropriate. Hasselbeck owns the NFL's lowest passer rating in play-action situations among quarterbacks with at least nine such attempts, according to ESPN Stats & Information. The chart breaks down the 32 qualifying quarterbacks.

"You really get a boost from getting a guy like (Lynch)," Hasselbeck said. "He brings something to our team that we didn’t have: a big, powerful, strong back who loves football, has a good football IQ, and complements Justin (Forsett) and what he does well, and so it’s exciting to have him."

Even when the Seahawks were an elite rushing team, Shaun Alexander wasn't known for breaking tackles or punishing defenses.
