The defense is reminding me of 2011

I think they could see some success running Fournette for sure - however I want to see how the run defense looks when the QB isn’t a threat to run like Mariota was.
Exactly. That funky little offense that Arthur Smith runs forced our defense to play honest. Running QBs and DA's scheme just don't mix. The good news is that as of right now this defense will only face a few more legit running threat QBs. They will be able to trust their keys and their eyes more against traditional rushing attacks.
