Jags already has said this line is more talented than the one in Atlanta.
Across the entire 32 team league - how many coaches are saying "yeah, we suck. We arent as good as XXXX. This player is not making any progress". ZERO.
Jones (an average back) had 1300+ yards with over a 4.0 average. THey had no QB or passing attack. So my opinion is that the running success had to come from somewhere.
Besides, the Bears are secretly practicing the ZONE BLOCKING SCHEME!!!! They are planning to be great this year! The word got out from PF.com on how great the scheme is and the Bears figured they might as well use it also.
