McFadden?? He is universally regarded as a huge bust. Can't stay healthy. The Raiders trusted him so much that they signed a washed-up Jones-Drew. As far as James Jones is concerned, he is a solid receiver. But he was a lot more solid when Aaron Rodgers was throwing him the ball. He hasn't made much of an impact yet for the Raiders. I don't even think he's starting (although he might tomorrow due to injuries). The Raiders offensive line is terrible. They let their best lineman leave (Veldheer). Etc., etc. The Raiders are a really bad team. I don't see any of this as a Dennis Allen-related deficiency.
On the other hand, the Dolphins have a pretty decent collection of potential Pro Bowl-quality players. Starks, Odrick, Vernon, Wake, Grimes on defense. Wallace, Clay, Pouncey, Albert on offense. The Dolphins do not have a talent problem at this point. They have a coaching problem and a QB problem. The two are related. I am completely convinced that if this exact Dolphins roster was coached by Andy Reid, Rex Ryan, Mike McCoy, Chip Kelly, Jim Harbaugh, Pete Carroll, or Bruce Arians, it is a playoff team.
