Totally agree with kontradiction and bobdigital in their last 2 posts, that's exactly what I think.
We are not asking too much, every NFL game a RB make a break for some good 40 yards. Obviously I don't want a RB with big runs and mediocre in the trenches with flawed stats. But If Ridley could make some runs at the exchange of no gains here and there he would still be productive. That's why we use this mathematical tool called average.
I don't think long runs are overrated, neither the deep threat WR. I don't think you build a roster with that I mind too, with an emphasis on these plays, but these are necessary plays we have been lacking for a long time. Good average numbers are good and guarantee you a playoff spot, from that point on you need a little more.
