Patriots' quick offensive line turnaround highlighted in PFF rankingThe New England Patriots' offensive line has gone from being considered a major weakness for the team to a potential strength. On the coaching side of things, the Patriots brought in an offensive line guru and former NFL head coach, Doug Marrone, to serve as the new offensive line coach. The offensive line rebuild is much further along than expected, four weeks into the season. The dramatic turnaround can be attributed to better coaching and finding the right personnel that fit the offense. For the first time in a long time, it seems like the Patriots are finally on the right track.
