When you look at the last several offseasons you see the Arizona Cardinals continually addressing the offensive line, but pretty much in the same way.
They bring in big named free agents who they get at a slightly discounted rate because they are banged up or coming off injuries: Jared Veldheer, Mike Iupati and Justin Pugh come to mind.
Or, they bring in journeymen types to fill in.
Then, in the draft they tend to find athletes who they hope someone can mold.
It has yielded nothing in terms of talent on the field.
