Did you happen to notice that that website lists virtually EVERY RB as having a High risk of injury. Adrian Peterson, Matt Forte, Jamaal Charles and Eddie Lacy are ALL listed as "high risk". You have officially reached "paralysis by analysis" mode.
No I didn't see that every RB had a high risk of injury. I finally saw the article that Rotowire mentioned. There were 5 guys: Arian Foster, Eddie Lacy, Ryan Mathews, Ellington, and Bernard Pierce.
They put Ellington on the list based on his past injuries and Arians making him his workhorse back.
That being said, Ellington has been drafted in the 3rd round (12 team drafts). Depending on how my draft goes and if I need another RB I would take him but would consider now taking Dwyer with a late round pick.
