Consider only the team situation. He's on a team that is bottom 5 in overall offensive efficiency, bottom 5 pass efficiency, and bottom 5 run efficiency. Then consider that he is sharing snaps with another RB at a 60-40 split. To top it off, Yeldon is 32nd in the league in success rate.
I couldn't give Yeldon away to the Chris Ivory owner for $1 of a $200 free agent auction budget. I have so little faith in him being able to produce in that situation and with his below average physical talent that I dropped him this week a roster space - and my RB room is RMathews, CThompson, DLewis, and KDixon.
