(Renton, WA)  --  Seahawks head coach Pete Carroll says his team has a lot of work to do to improve its offense.  Seattle scored only one offensive touchdown in Sunday's five-point loss in New Orleans, and is ranked 29th in the NFL in points per game.  Carroll says he feels his offense will improve as quarterback Russell Wilson continues to recover from knee, ankle, and pectoral injuries.  The coach says Wilson has been limited in running with the ball while healing from those injuries.
