from very good insiders that I read say Cox was looking very good in workouts and one of the better backs at catching the ball and turning up field.
Like others on here have already pointed out, look at RR's past and how he has used big backs.
The more I hear of GBMW and what is on the blog, the less I think of their insider info and opinion. Maybe he does go to defense someday, but I would like to make a bet with them and I'll go with him sticking to offense based off of everything I've heard this spring.
Would be nice if you could make posters of whoever on the interwebs put their money where their mouth is to back some of the things they put out there.
