This was my post last August:
This year the Rams will go with a running back by committee approach. I'm curious how much of what I see is shared by my fellow fans. The following is my evaluation of where each rank in the following catagories.
Long speed: 1 Richardson 2 Pead 3 Cunningham 4 Stacy
Quickness: 1 Pead 2 Richardson 3 Cunningham 4 Stacy
Ability between the tackles: 1 Stacy 2 Cunningham 3 Pead 4 Richardson
Yardage after contact: 1 Stacy 2 Cunningham 3 Richardson 4 Pead
Pass Pro: 1 Stacy 2 Cunningham 3 Pead 4 Richardson
Versatiltiy: 1 Cunningham 2 Pead 3 Stacy 4 Richardson
Experience: 1 Richardson 2 Pead 3 Stacy 4 Cunningham
Hole recognition: 1 Cunningham 2 Stacy 3 Richardson 4 Pead
Receiving: 1 Richardson 2 Cunningham 3 Pead 4 Stacy
Ball security: 1 Stacy 2 Cunningham 3 Richardson 4 Pead
Interestingly, in a cumulative score, I get the following numbers:
Cunningham 22, Stacy 24, Richardson 26, Pead 28
I'm not sure what it all means but I'm willing to bet I'll get a few people to sharpen my thinking on the matter.
Amazingly enough, the regular season performances mostly vindicated my perspective. And even though Cunningham continued to have better stats per carry, Stacy's skill set better fit what that offense needed last year as he's better between the tackles, blocks better, and gets more yards after contact behind a generally weak interior offensive line.
As to the OPs question, Pead's skill set offers nothing more than what T Austin can provide. Both are "space only" players who thrive on making people miss in the open field and frankly, Pead isn't in Austin's class in this regard.
What's curious to me is where Mason fits. I think that's the greater mystery. At first blush, my guess is that he is here to provide the skills they hoped from Richardson and Pead. He may not be as quick or fast, but he seems more instinctive and more difficult to tackle. I still don't know which player fits a screen game which this offense rarely features but I think should improve.
