AZ is known for being really undersized on D and they consistently have one of the worst defenses in the country. How you came up with that, I have no idea. They're not awfully talented and they return their same DC. Some will complain that so do we, which may or may not be our disadvantage, but Sitake will be more involved this year as well. BYU was bad one year on offense and people lost their minds. AZ is awful on defense consistently. That's not an overnight fix. I question if they'll even make top 100. Maybe because they return young guys but they're not making some huge jump.

Oh and they don't know what their offense will look like either.

I'm mostly messing around because I know Tate is a killer athlete, and JJ Taylor is good. And I have no idea what a guy like Sumlin is going to do to take advantage of it. And he's known for starting seasons well and then crumbling, and we're at the beginning of the season.
Basically just saying AZ is far from perfect. They weren't a very good team and they do return a lot, but they have work to do.
