Poor line interaction has to do with improper technique, not properly utilizing the rush moves, and poor attempts by the Dline to get seperation, which leads to lots of patty caking. The emphasis is mainly on the Defensive line not doing what its supposed to do ( mainly the DE's) not the OL.
Putting kickers on the OL and having them perform as well as OL men shows that strength, and blocking ratings are irrelevant.
Besides, my response was to someone who claimed that putting kickers on the oline only works on all madden, it wasn't a post to prove that ratings don't matter....
