The Seahawks have begun addressing their offensive line needs in the most elementary way this offseason. Seattle has let go two underperforming players in Garry Gilliam and Bradley Sowell. They may move starting guard Germain Ifedi to tackle. They signed Luke Joeckel and may trust that he can be good at left tackle. The Seahawks have not proven they can yet be solid in 2017 at tackle, though.
The problem is the 2017 draft does not have a superstar at the position. For instance, Walter Football ranks Cam Robinson as the number one tackle in this draft but states he may not be taken until late in the first round.
