I know, it seems like every year is "the year" for Shonn Greene to break out. The truth is, Greene was never given the proper situation to succeed. Last year, Greene's first season as the lead back, the Jets decided to become more of a pass-first offense, which yielded disastrous results.
In addition, the health of his offensive line, particularly on the interior, was questionable at best. Nick Mangold missed two games at center, and in one of those games against the Ravens, the Jets had just 35 rushing yards.
On the right side, Brandon Moore was one of the best pass-protecting guards in the game, as he did not give up a sack all season. However, he was rated one of the worst run-blockers in the game by Pro Football Focus.
This is probably due to the surgery he had last offseason that caused him to miss some time in training camp. While he was not able to get the same kind of leverage as usual, he is a good enough technician to have still played at a Pro Bowl level.
At the end of last season, the other Jets guard, Matt Slauson, revealed that he was dealing with some serious shoulder issues. The injury clearly had an impact on the amount of power he had in the run game.
With a healthy offensive line and playing in a run-first offense, the stage is set for Greene to take off in 2012.
