Addai joins a running back corps that's somewhat crowded with the likes of Danny Woodhead and two second-year players, Shane Vereen and Stevan Ridley.
Some might speculate that Addai will bring some stability to New England's backfield, considering the loss of BenJarvus Green-Ellis via free agency to the Cincinnati Bengals.
The 29-year-old Addai has been dealing with injury problems over the past few seasons as he's played in just one full NFL season—and that was back in 2006, his rookie season. The addition of Addai to New England's backfield brings a seasoned veteran that has been involved in a winning environment with the Colts—and not to mention, experience in a pass-rush offense.
Addai is not only a solid running back, but he's a great receiver coming out of the backfield and is one of the better pass-blocking running backs in the NFL as he's very good at picking up blitzes—something that Green-Ellis flourished at.
Addai's greatest success came in 2006 and 2007 as he eclipsed the 1,000 yard mark in both seasons while scoring 19 total rushing touchdowns as well as reeling in a total of 81 total passes and compiling a grand total of 2,842 total yards.
This will be Addai's seventh season in the NFL as he was selected the same year that Bill Belichick and the Patriots drafted Laurence Maroney. They passed on Addai at No. 21 overall, and he was ultimately selected at No. 30 overall by Indy.
The addition of Addai might mean that we have seen the end of Kevin Faulk in not only a Patriots uniform, but in the NFL entirely, as he's turning 36 years old this summer. Addai will likely fill Faulk's role as the veteran leader of the running back corps and will be as versatile as Faulk was—as long as he's healthy, of course.
All in all, this is a pretty solid transaction on the Patriots part. If Addai can stay healthy, he can be one of the more lethal running backs in the league due to his ability to catch balls out of the backfield as well as being a traditional in-between the tackles running back.
