Tom Cable put that OL together and now he is 3 years removed from the system, so his stamp is no longer on it. The same coach who went to Seattle and turned their line into one of the better O-lines in the NFL.
Also, the Raiders were doing very well in 2011 (7-4) before they crashed and burned, which tells me they were a better team overall in 2011 than they are now. Finished 8-8. They won't sniff 4 wins this year...........
But good luck with McFadden. It would be fun fantasy wise to see him do well.
