They didn't pay those guys big salaries. They got lunch pail type deals. These guys are getting premium salaries, so it is logical to assume that these guys are premium players. They will be great, the Buffalo Bills know what they are doing. A lot more than any one of us who don't evaluate talent for a living. Imagine how much more tape the talent evaluators have seen over a Raiders fan guy watching the whole game and not focused on just Walker. Maybe loaded with beers to boot.
