The Seattle Seahawks want to make sure other teams feel quarterback pressure. Sure, stopping the run is important, but Mike Macdonald's defenses haven't always ranked in the top-10 in terms of yards allowed per rush. Somehow, they still rank in the top 10.
This is because Macdonald knows which players fit his system best, and which are likely to be the most versatile within the scheme. Veteran DeMarcus Lawrence was signed, for instance, not just because he has a history of chasing down quarterbacks, but because he can set a hard edge against the run.
The Seahawks must think undrafted free agent Jared Ivey can do that, too.
