Without a doubt.
While I definitely like Raheem Mostert a lot and his effort (along with JW) against the Jets got us to the playoffs last year in that win against the Jets. Those guys didn't have to deal with stacked boxes.
Taylor changes the dynamic completely. You can't afford to be in nickel and dime all the time with him on the field and if you are, good luck.
Taylor-Hill-Waddle would be better than Holt-Bruce-Faulk that the greatest show on turf had. Taylor is a better RB than Faulk but Marshall was an elite level receiver. I was a fan of Bruce/Holt, they did it the right way. Hill and Waddle just have more juice.
