The NFL has changed and the rules are different than they were 10 years ago. Back then investing a top 5 pick on a RB was the smart move given how the league was. But today in a pass first league investing a top 5 pick at a position where the shelf life is on average 5 years seems like a waste. I would argue that you could get nearly similar production in Rds 3-5 while you use that top 5 pick at a more impact position (DE, QB, S).
We were primarily a passing team prior to 2014, and where did that get us?
We had Romo's arm, we had TO, we had DeMarcus Ware and a bunch of average running backs, and where did that get us?
We need to start taking dynamic players - WHATEVER position they play.
Too many fans are worried about five years out. Well, the draft comes around every year. Outside of the quarterback, I don't care what Ezekiel Elliott can do beyond five years. I care what he does in his first year. And then I'll move on from there.
Besides, Jason Garrett wants to run an offense similar to the offense we ran in the 90s. And that offense was run-dominated. Emmitt made that offense go (Derek Lassic couldn't do it, Sherman Williams couldn't do it. Blair Thomas couldn't do it, and a bunch of other journeymen running backs couldn't either).
If Ezekiel Elliott can give us an Emmitt-like impact, take him. Last I checked Cortez Kennedy, Junior Seau and Keith McCants didn't win their teams any Super Bowls.
