I think my original point is that Dareus is our best defensive player, and losing Kyle and AW is not as bad as losing Dareus.
We had two key players also hurt for much of 2014. We just didn't crumble when they went down.
And the injuries maybe give Rex some more leeway, but it's a case of differing between bad and really bad and awful. Schematically, he really struggled. The degree of which is debatable.
