"Should reserve running back Justin Forsett's recent success be that much of a surprise?

The shifty, second-year runner out of California has been a godsend for a Seattle Seahawks running game needing a jolt. Forsett has jump-started Seattle's offense, rushing for more than 100 yards twice in the past three games.

But in the search for a key to his success, look no further than offensive coordinator Greg Knapp's zone blocking scheme.

Forsett has been playing in that system since his freshman year with the Golden Bears. It's no wonder he darts through holes like he has seen them before.

He has.

"I came from the zone blocking scheme from Cal so I've always been comfortable in it, and I think it suits me well," Forsett said. "And we're starting to get it rolling now, so it feels better."

How well is Forsett going? So well that Seahawks fans are shouting that he should be the starter over injured running back Julius Jones, who has missed the past two games with a bruised lung suffered early in the Arizona game.

And they have a point. For the season, Forsett has 385 yards on 68 attempts for a 5.7-yards-per-carry average. He's fourth on the team in receptions with 29 for 246 yards.

"Any time you get your hands on the ball you want to make something happen," Forsett said. "I just want to be a spark plug. As many times as they give me the ball I want to be able to do something with it, and I'll be productive."

Jones has rushed for just 392 yards on 107 carries for a 3.7-yards-per-carry average.

However, most of Jones' carries came behind a makeshift offensive line early in the season. Forsett has benefited from a healthier offensive. So the Seahawks brass would like to see how a healthy Jones would do under the similar conditions."
