The Giants worked out free agent RB Joseph Addai on Tuesday.

A league source tells CSN New England that Joseph Addai "quit" his conditioning test after struggling to complete it. We suspect the other 31 NFL teams will now be even more hesitant to take a chance on Addai, as his commitment level will be questioned. Much like Clinton Portis last summer, Addai has reached a point in his career where he's essentially a blitz-pickup specialist with little to offer as a runner. It's fair to question whether he'll play another snap in the league.

Patriots released RB Joseph Addai. The Pats wound up sinking $125,000 into Addai in the form of a signing bonus and offseason workout bonus. Addai was never going to help the Patriots as a ball carrier, but the 29-year-old can still pick up the blitz and always seemed likely to at least last into August. He didn't, which can be taking as a sign that Addai's career is on life support. New England will move forward with Stevan Ridley, Shane Vereen, and Danny Woodhead atop the depth chart.

According to the Boston Globe, "word is" Joseph Addai wasn't impressive in the Patriots' offensive program. The Globe apparently took the "word" seriously enough that it doesn't project Addai to crack the Patriots' 53-man roster. ESPN Boston's Mike Reiss opined in June that Addai would likely go down as "one of the Patriots' best free agent signings," so there's clearly a difference of opinion on his future in New England. Barring a catastrophically bad preseason, Addai should have an inside track on a roster spot.

ESPN Boston puts Joseph Addai's chances of cracking the Patriots' 53-man roster at 80 percent. Reporter Mike Rodak believes Addai's closest competition for a roster spot will be Danny Woodhead, and reiterates he isn't expected to be a big contributor outside of pass protection. Provided Addai is healthy and doesn't look completely washed up in the preseason, he should break camp with the Pats.

According to ESPN Boston, Joseph Addai was signed primarily due to the Patriots' renewed emphasis on improving blitz pickup this season. "If all goes according to the coaching staff's plan, you'll be hearing a lot more about Stevan Ridley and Shane Vereen this year," writes ESPN Boston's Mike Reiss. The implication is that Addai will be limited to Kevin Faulk's old role as Tom Brady's personal protector on passing downs.

ESPN's Mike Reiss thinks RB Joseph Addai will go down as one of the Patriots' best free agent signings. Cimini calls Addai a "low-key, versatile, mentor-type professional" who compliments the younger Stevan Ridley, Shane Vereen, and Danny Woodhead well. Assuming Addai makes the team, he'll only see a handful of touches if everything goes according to plan.

Joseph Addai's one-year deal with the Patriots contains a non-guaranteed base salary of $725,000 and a roster bonus of $218,750. In other words, Addai will have to earn his roster spot in training camp and preseason action. While he does receive a $75,000 signing bonus and a $50,000 workout bonus, the Pats are unlikely to pick up that roster bonus in September if he doesn't prove to be a more reliable option than Stevan Ridley and Shane Vereen.

ESPN Boston's Mike Reiss does not consider Joseph Addai a lock to make the Patriots' roster. The Patriots carried five tailbacks last season, but could go with fewer this season after adding a third tight end, a trio of fullbacks, and a long list of veteran wide receivers. Still, it's unlikely that New England will head into 2012 with just three tailbacks, so Addai's roster spot should be safe. At best, he'll see a handful of carries and third down work. At worst, he'd simply be insurance behind Danny Woodhead, Stevan Ridley, and Shane Vereen.

Patriots signed RB Joseph Addai, formerly of the Colts. Addai visited the Patriots last month, but otherwise received no other known interest on the free agent market. In New England, Addai's primary responsibilities will be relegated to third-down situations. Stevan Ridley remains the leading candidate for early-down work, while 2011 second-round pick Shane Vereen and Danny Woodhead are complementary, change-of-pace options.
