A few highlights from Seahawks offensive coordinator Greg Knapp's most recent appearance on John Clayton's weekly Saturday radio show in Seattle:
Quarterback Matt Hasselbeck will continue to have flexibility in changing to running plays at the line of scrimmage, an option he used when Mike Holmgren was head coach.
The Seahawks will favor personnel groups with one running back, two receivers and two tight ends. They will also use three-receiver groupings with one back and one tight end. It all adds up to less playing time for the fullback, one reason the Seahawks didn't make a big play for Leonard Weaver in free agency.
The Seahawks might have an easier time identifying blitzes now that their base offense will not feature two running backs. Defenses have an easier time disguising intentions when the offense uses two backs, according to Knapp.
Tight end John Carlson is working to improve his lower-body strength to become more effective in the running game.
Knapp contends an offense needs two fullbacks and three halfbacks on its 53-man roster. That is fairly standard. The Seahawks kept a sixth running back [Justin Forsett] entering last season. They carried five on their previous four opening day rosters.
