I'll buy one out of three with the injury, but NOT the other two. The injury and his age effected his speed, but following his career under Holgrem, CMH has babied his QB and slammed Alexander every chance he got. Shaun is the consumate professional. He wouldn't air the dirty laundry publicly, but if you worked for a a$$ like Holmgrem and got very little support, perhaps your drive wouldn't be the same.
As for "hands", anyone ever watch Hasselbeck throw to a RB? Shaun had over 400 yards receiving his Sr. year.
DO NOT question his competiveness. He played through a stress fracture in his foot until he finally made it worse. Some GM will see through Holmgren and give Shaun a shot. He may never be Shaun the great again, but I still believe, given the right oppertunity, he could be a top 12 back.
