I think a lot could be contributed to the fact that Levy was a special teams coach himself and placed a lot of weight on it. Afterall how mant other Head Coacheswould stay after practice and work with a WR just picked up off the waiver wire from the Oilers on punt blocking?
Not sure about this, Nix did say after draft that if the opposing teams offense starts on their 20 yard line it really helps The Bills Defense.
