According to ProFootball Weekly, the Pats are going to change their run blocking scheme from a straight line blocking to a zone blocking to accomodate Maroney's cutback style. I think this is big. People blamed Maroney for not hitting the hole fast enough late in the season, but I felt the o-line wasn't opening up holes for Maroney in a lot of cases. Now that they will zone block, it will allow him to shift to hit the hole. I think assuming he is healthy, he can only be better behind this blocking.
