Buddy was the Director of Pro Player Personnel for his first year with the Chargers, but after Butler died, Smith was promoted to General Manager, and Nix to Assistant General Manager. Your challenge is fair - I can't say that Buddy pulled the strings, as he reported to A.J. Smith. I did read that Nix was one of the major draft-day decision makers for the Chargers, which would imply that it was a team approach, rather than a one-man show.
In any case, he has experience in a winning program in San Diego, and I would love to see similar results here in Buffalo.
