I think the NFL will miss John Butler, the 56-year-old Chargers GM who died of cancer on Friday. I really liked Butler, even though we had a major falling-out late in his tenure in Buffalo. This is why I liked him so much: He was a big man in so many ways. We hadn’t spoken for three years until the Friday before this year’s Super Bowl in San Diego. I was at the Chargers facility, in their front offices, doing the media pool report while covering the Raiders, and I ran into Butler. He was angry with me because I had agreed to be a regular guest on the radio show of a former Bills coach, Chuck Dickerson, who often was brutally frank and critical of the Bills.
