It would be really cool to see stats on which teams are the better pass/ rush defense. The ranking the passing/ rushing defense could be determined is average yards per play or game. Anyone thoughts?

Go to the league standings page. Click Team Stats. Select what stat you want to see. It's there.

I don't see much stats on how many yards defenses limit per possession. I mean more along the lines of say pass knockdowns per game, or successful first downs per game. But I won't make too much of a deal out of it, I guess there's enough stats there..

I thought you were wanting just basic run defense/pass defense stats. I'm all for expanding the depth of the stats provided. Tackles for loss would be nice...... WR targeted numbers...... Two I would personally like to see.
