I thought I read somewhere on kickoffs saw an increase in LB, TE, safeties and RB's. More reassembling running plays and needing open field tackling.
WR still used on punts. Maybe a bit less important to need WR's for specials?
It can mean that to you. It can also mean you're among the best right now and Cook is. He's certainly, for this discussion, one of the players that makes the Bills - not just Josh being one of the best at his position.
My son is a server at a restaurant McDermott frequently visits in Charlotte. He finally got a chance to speak with him a couple nights ago. He was very nice and mentioned Josh is as advertised and will always root for him and Buffalo to win a Superbowl. He was in general soft spoken and his wife talked more than him.
Coached his arse off you say? Twice he got embarrassed by Payton, with a TD pass in iso the play immediately following an injury to a CB. He strategically sucked and got clowned.
Beane is doing what a GM does when it's decided they have their QB and/or team to try and win a championship. This is nothing unusual. He's used every lever before. They'll be more levers next year, the year after and year after, etc.
