You are also missing the point that it is an easy offense to defend.

The Jags throw primarily out of 1 and 2 wide receiver sets outside of 3rd down. Most throwing downs we max protect and release maybe one player into only checkdown routes. The receivers run the same basic routes (Lee is the only one who has a route tree that takes him over the middle more than occasionally). The first quarter we throw disproportionately less on 1st and 2nd down and primarily in 3rd down situations. These are things that are abundantly obvious to the ley observer, let alone a defensive coordinator who is game planning. It's incredibly conservative until 3rd downs or we are down scores.
