Russ did win a superbowl and make it to another with SEA so I don't know how 'wasted' his years were. Could he have done more with a better O line, probably yes. Could he have accomplished more with better play calling, probably yes. But wasted years? Other QBs from that draft: Luck, RG III , Tannehill, Cousins, Weeden, Osweiler=0 superbowls. Others Foles with one. A Rodg only has one.
There is a rumor floating around that Pete might move into a front office job. The question though is, who is a better coach for SEA? Eric Bieniemy? We have no idea how any of the assistant coaches will be as head coaches. I guess we know EB's O mind, and he has learned under Reid, but that doesn't guarantee that he will be a good HC.
