Overly reliant on scheme and blocking to open holes, McFadden could surprise with a bounce-back season behind Dallas' dominant offensive line.
"The kinds of skills that got (McFadden) drafted with the fourth pick in the draft," Jones told PFT Live, "he still has."
"You worry about injury (with McFadden), but we were worried about injury with Murray," Jones explained. "In eight seasons, four in Oklahoma and four with the Cowboys, Murray only had two injury-free seasons.
"And so the position is one you have to take into consideration no matter what the skill level is, they take a lot of hits, lot of punishment, and you got a good chance to have an injury issue. And that's why we couldn't make that kind of commitment of dollars to that position."
