Appreciate the analysis. Which games did you view for McFadden? I feel behind without All-22. I'll be honest I'm not excited at all about him, but this helped a smidge.
I don't know about the OP, but I've studied multiple of McFadden's games with the Raiders using the All-22. I focused on 2014 but I also reviewed some games in past seasons.
I didn't see any physical decline.
He is still very fast.
He is a terrific pass blocker and IMO, better than Murray in this area.
He is a very good receiver.
McFadden is not the best RB to have with a bad OL. He needs a couple of steps to get going because he is a biy of a long strider. This is somewhat true for Murray as well. With a bad OL it's better to have a dancing type RB. Murray and McFadden are 1 cut and get up-field type RBs. The Zone blocking scheme allows the RB to be on the move before making his cut, so in theory it should be good for McFadden.
In regards to vision, it's honestly difficult to evaluate because he was hit behind the line so often. In general I didn't see any problem with his vision. Murray's vision was average at best.
In regards to power, McFadden ran with power and didn't shy away from contact in his earlier years. In 2014 I did sense that he was more likely to avoid contact than he had been in the past.
The primary problem with McFadden is the injury history.
The 2nd question is his 1 year in the Zone Blocking scheme. That didn't go well so it is a concern. It's odd, because his style (1 cut and get up-field) seems perfect for the ZBS. Generally the 1st year of a Zone scheme is a problem. It is normally the 2nd year before the OL really adapts to it. Murray's lowest average was in 2012 which was the 1st year of the ZBS in Dallas. Also, not only does Dallas have a much more talented OL to implement the ZBS, but it's probably a more evolved scheme than what they were using in Oakland. The Cowboys use both the ZBS and normal Power-Man blocking in their running game equally well.
Summary: McFadden is still a really good player, but must stay healthy and must prove that he can be effective in a Zone scheme; although the Cowboys have the ability to run Power Man run blocking equally as well as Zone.
