If Jonah is done, that puts Josh Simmons in play for round 1. That's if he wasn't already in play.
I had the Cardinals taking Simmons in my way too early offseason plan with the #16 overall pick, assuming that Simmons drops that far. The thought of having a pair of young stud bookends in place for several years to come is very tempting.
You have to protect your most valuable asset, the franchise QB. Whether that ends up being Murray or some other young QB of the future.
