Denver's stacking the line every play and why not. We either run it into the pile or check down. Until we try a play 5+ down the field, they'll keep it up.
I'm not an apologist for Trent, but that hit on him certainly looked like a "top of the helmet" hit. Problem is when you're at the bottom of the league, you don't get those calls. That happens to Cutler and we're flagged.
