Addai's release comes as a major surprise to me, as he was projected to be the team's "veteran presence" in their very young backfield. Young and coming backs Stevan Ridley and Shane Vereen both lauded Addai's strong veteran presence during offseason workouts. He was projected to maybe serve in a third-down back role with the Patriots in 2012. This could be good news for Danny Woodhead, who was also competing for that third-down role.
His release makes me believe that he either didn't show well in his conditioning test today, or he has a long-term injury. The loss of Addai means that the Patriots can add one more player before they begin Training Camp on Thursday.
With Addai gone, the Patriots have Ridley, Vereen, Woodhead and undrafted rookie Brandon Bolden as the only running backs on the roster.
