Roy hasn't been mentioned at all any legit trade scenario. The one pulled from the Ranch last year doesn't count. I look at it like this. It would take losing Roy to determine how much of a loss it would be not to have him on this team. Until then, I don't know how anyone can definitively say, "it wouldn't be a big deal to trade him" or on the flip side, "the team would go down the tube."
Roy is just getting to that point where he, T-New, and Henry form a pretty solid group of vets in the secondary. The secondary is extremely young and talent-limited behind them. I wouldn't want to trade him and then start the season with a rookie, Keith Davis, 2nd year man Pat Wakins, and some scrub vet.
However, there's a ton of smoke regarding Julius, so I don't discount that. I like Julius and I hope we see more from him next year. If not, then I see the need to draft another running back. Not until then.
