I'd say pretty much everything is media speculation at this point. At a school like Georgia, with so many talented players, every team is well versed on their prospects.
I only say it because Walker appears to be the higher ranked guy on everyone's board. Various podcasts have talked about Walker being a realistic possibility, and maybe the best pick, for the Jags at 5. And as far as the Patriots go, with Vrabel/Belichick background, people think he would like and be able to use a versatile piece. But thats just my speculation.
