Randle had four impressive games last year, Seattle, Chicago, Commanders, and Jags. Three of those games came when Murray wore down the defense. He also had 50 carries, not hard to have a high average with that amount of carries. Look at the statistics, against Houston he a 2.2 average, against Giants, 3.5 average, against Arizona a 2.0 average, against Philly 3.0 average, against Indy (On 13 carries, his most in a single game) he had a 2.8 average. It's easy to have a high rushing average when you have games where you averaged 17 yards on limited touches.
There certainly was a dropoff between he and Murray, and defenses were far more keyed in on Murray.
I won't argue that Randle had a much easier chore not having to play the first few series. He ran into 9 man boxes against Indy 13 times but most times got a half dozen or so carries.
He looked very quick getting to the hole where the year before he was sluggish. He improved dramatically in that regard from 2013 to 2014. He can juke in traffic and shake people at the point of attack. He can also cover a lot of open ground laterally with those jump cuts when he gets in the open field or to move across the formation on cutbacks. He's not big but he has very good leg drive and balance to push through contact. He can get low and push piles, run through arm tackles keeping his feet. He still might not have even peaked in terms of physical talent: he doesn't turn 24 until December.
Keeping that type of effort for 200 carries is a whole nother level of challenge than 50 but I am fine with the above for 10+ carries a game and seeing what happens. If he sucks then take him out but he is a pretty good prospect in my view for all his Dillard's robberies.
He is pretty efficient in pass protection but his passing game is pretty much leaking out to the flats or the middle of the field and screens. He has very good hands. Has a lot of room to get better here.
Ideally you would rotate series or situational and have no one get more than 200 carries.
Looked at another way would, where would you rank Randle in this year's draft? I have Gurley, Gordon, and Yeldon as clearly better. That's it.
Where do you put 25 year old Ryan Williams assuming his knee checks out? Is with Ajayi in the 5th? Better than that? Where's Dunbar?
There were two instances where RB were coming at them in Johnson in the third and Davis in the fourth. They did not feel compelled to trade up to get either. They didn't bring in either to visit either. I think you can infer that the Cowboys think that at last some of their current prospects are better than them.
