RB's aren't a dime a dozen at all, but that doesn't mean that you reach for a good one. It's all about system fit nowadays. Motor fits. His ypc is really nice over the years. You could probably put him on a lamer team like the Commanders and he might churn out 1200 rushing yards (I think he's better than Gibson at this point) but it wouldn't matter anything to them because they'd still be terrible.
I think most agree that RB is very important, it's just not the gaudy stat producing position of the early '90s (Natrone Means knows what I mean), and you also don't usually need to pay very much for somebody serviceable. I'm perfectly fine with our group over Saquon or McCaffrey.
