One more thing on the Young /Simmons debate.
There's another cause and effect consideration that comes into play with respect to Young and not so much with Simmons. Extra attention to Young because he will be a constant fixture has to have a positive effect on his teammates play. Simmons will line up where plays are designed and not necessarily always as a linebacker. As a pass defender, he could buy a little more time for the front line guys, but the immediacy of Young helps most.
