Barlow has been stuck behind a shitty Oline in SF, but I think he probably still has some good upside. SF has Frank Gore and a couple other young runners that they are high on. SF just traded CB Mike Rumph to Wash for WR Taylor Jacobs, how about if we send them CB Derrick Strait (to replace Rumph) for Barlow? I could live with that.
I don't think SF is going to move Barlow. First of all, Gore is coming off of surgery so they won't do anything until they're sure about his status. Barlow is also coming off of a knee operation, although he has looked good so far. Their other RB is Maurice Hick(s) who doesn't seem to be starting material. I don't see it, but who knows...
I'm not really a Barlow fan and I don't really think that San Francisco plans on moving him anyway. I doubt that any of these guys are getting seriously shopped either, but the Jets should call the Vikings about Mewelde Moore (I've read that they like Fason a lot, I'm looking for that link now), the Rams about Moe Williams (he's their 3rd back behind Jackson and Fisher) and the Raiders about Justin Fargas.
Only if he was really cheap. He's the classic example of the more carries he gets, the worse he does.
