He is a good player when healthy. There is no way to predict his health, but he has enough talent to succeed.
His is very good in pass protection.
He is still faster than Murray.
He has not fumbled much.
They won't give him the same amount of carries as Murray even if he is healthy. They really like Ryan Williams and will like add a RB in the draft.
His total yards from scrimmage in the running game is 4247 in seven years. Murray's is 4526 in four.
With his speed his longest from scrimmage was 70 yards. Murray, the slower of thew two, and an aspect you harp on was 91 yards.
He has averages 4.1 per carry while Murray has averaged 4.8.
He has posted 1 1000 yard season. The other six seasons he has not broken 708 yards.
He averages 11 games a year where he can suit up.
You have been one of the more vocal proponents of Murray leaving. I don't suspect even with that becoming reality you endorse McWastrel, but even so, you are here defending him against a real rushing threat using this fumble category and speed ti suggest he has an upside Murray does not.
There is absolutely nothing about Darren McFadden which suggests he could carry Murray's jock strap.
