A lot of blame and attention is given to the O-Line. One of the things that have seemed blatent is that our RBs and especially Freeman are missing a lot of assignments in the pass blocking schemes. It is fine to be after Garreth Holds but when Freeman stands alone in the pocket, both tackles are beat and no one is near that is a huge problem.
DT in many interviews said that one of the things he took most pride in was blocking - and it does not seem like brains, coaching, scheme... whatever is working.
