Jackson, who was released by the Falcons in February, recently said he is only willing to sign with a contender, ESPN.com reports. Jackson likely has his eyes on a backup role with a top-notch team, but he may have a hard time finding the right fit. If nothing comes up, it's possible he'll retire, as his 32nd birthday is in July. Jackson averaged just 3.7 yards on 190 carries for the Falcons last season, and while he's unlikely to get that many touches in 2015, he may be able to find a decent team with a better offensive line.
