Nearly every offensive position on the Seattle Seahawks comes with question marks. Some are innocuous, like whether Tyler Lockett or DK Metcalf will be WR1A or WR1B. Some are more significant, like if Mike Iupati or Will Dissly can play more than six games.
We can add in plenty more for fun: does Seattle have (or need) a third receiver? Will the Seahawks let Russell Wilson cook? Is Pete Carroll even capable of calling a good timeout?
Lots of questions on this offense, but who runs the ball is not one of them.
