Based on scout ratings, the better player is not pretty obviously Bell, if we're talking about talent. Gurley consistently has received much higher ratings than Bell.

Le'Veon Bell's scouting ratings are about as relevant as Tom Brady's or Antonio Brown's at this point. It's very clear that they are outdated. Bell dropped the weight and is a totally different guy now. Everyone on this board noticed it and, for the 10th time, vaulted him up their dynasty rankings BEFORE he put up elite production. He has a burst and lateral agility that he never showed as a prospect. If he re-tested at the combine now he would perform much better. And none of that accounts for how overlooked his vision and receiving ability are, much like we can't just ignore how much Tom Brady's knowledge of the game and ability to read the field was overlooked as a prospect.
He is going to need 80 receptions each season to maintain top-5 production
This is a ridiculous statement. He had 80 receptions last year and outscored RB5 by ONE HUNDRED fantasy points. You could cut his reception total in half and he'd still be comfortably in the top 5. I agree that his receiving numbers will likely regress to the mean some, but he has to lose a LOT of receptions to drop out of the top 5. His rushing numbers were in no way unsustainable. If he can maintain that you could literally cut his receiving numbers all the way down to 40 catches for 400 yards and he'd still be in the top 5, comfortably.
But, hey, if you're in the business of grabbing lesser players with the assumption that a good situation will always be a good situation and support that lesser talent, more power to you.
You're obsessed with trying to create an argument that's not there. People aren't arguing that situation > talent. They're arguing that you're vastly underrating Bell's talent. Maybe not quite as talented as Gurley but close enough that his other advantages (vision, receiving ability, past production) make up the difference.You're inventing a narrative that isn't there. The reality is that people were blown away with Bell's talent last year, not his production. Again, right out of the gates last year people were WOWing their eyes out watching him run, before the production came along to match. Yet you're content to ignore that and have decided that since he wasn't quick and agile 5 years ago at Michigan State he must not be quick and agile now, just like you must have assumed that since Tom Brady was considered to have an extremely weak arm as a prospect he must have had an extremely weak arm for his entire NFL career.Fat plodder Le'Veon Bell is as dead and gone as noodle armed Tom Brady or slow cutting Antonio Brown. He dropped the weight and got in shape and his burst now gets him through the holes that his elite vision have always seen but that his gut slowed him down too much to get through in time.Stop arguing like this is simply some matter of uber talent vs. average guy in a great situation because the only one you're arguing with about that is yourself.
