Simple answers to simple questions: No. But the Green Bay Packers might sign RB Cedric Benson anyway, as was reported by Ian Rapoport at NFL.com, and they (hopefully) have a good reason.
While I don't believe this line of thinking, here's why he could be a good signing. I questioned last week whether James Starks was really the answer, and pointed out that there isn't a strong Plan B on the roster. Cedric Benson has shown great athleticism and production in the past, and a strong work out could be a sign that he still has some game left in him. After weak performances by Starks (5 carries for 16 yards) and undrafted rookie Marc Tyler (13 carries for 32 yards) in their opening preseason game, they understandably might want an upgrade.
On the other hand, there are many reasons why he's not the answer. He has rushed for over 1000 yards each of the last three seasons, but he's done it while averaging under 4 yards per carry. Football Outsiders had him ranked near the bottom of the pack last season for good reason: his low ypc and his tendency to fumble. I double-checked their section on him in the 2012 Football Outsiders Almanac, and there's nothing positive to recommend him there either.
Other red flags abound, he's frequently in trouble with police and he's on the wrong side of age 30, but his fumbles, on a team that prides themselves on winning the turnover battle, is my biggest concern. However, he might not be given more than 150 carries even under the best of circumstances, which would only add one or two more fumbles (potentially) over the course of the season.
It's disappointing to see his signing receive serious consideration, they should have planned this better during the offseason, but his arrival wouldn't have a major impact one way or another.
