As the article stated Ben was having one of his best years before the injury, and with this type of offense Linemen don't have to hold blocks as long. I think we just need a solid run game to compliment Haley's offense.
The misconception is Ben can't throw down the field, he can but not like he did under Arians, having a run game will help balance this offense and keep defenses guessing.
If you noticed Ben distributed his passes more under Haley as Miller was having a great year, and even fullback Will Johnson caught some passes. I think with a second year we should see improvement, having Ben healthy is key though.
