I'm not sure I've ever seen Chubb run the ball and thought "I bet [name a different running back] could have gotten more out of that play". Every single time he runs the ball, I think he's getting the most possible yardage out of the play.
I'm sure someone can find the odd play here and there where he missed. But it would be a damn rare thing. He's HOF good right now.
At this point It seems like a general consensus that Chubb is the best pure runner in the league. McCaffrey and others do provide value in the passing game which is obviously huge and makes them a more versatile chess piece, and why they are paid such exhorbitant amounts of money. In terms of just pure running ability Chubb is virtuelt in a class of his own, though, with the only other arguable contender being Derrick Henry.
The Browns have signed the best running back the team has had since Jim Brown. Why are people criticizing the deal? Criticisms largely say that it is too little for Nick Chubb or that it is a waste of resources for the Browns. Let's let the numbers decide.
