Spector is an idiot. Nothing new here.
Just yesterday someone tried to argue Dale Tallon was the reason for the success of the Florida team, and not Bill Zito. The "insert name didn't build this team because insert name built this team" argument has always been tremendously flawed to me, and just an incredibly simplistic way of looking at things.
1) Every GM inherits pieces from the previous GM unless they are hired by an expansion team. Everybody always brings up what Gillis inherited from Burke and Nonis. Yet they don't mention that Burke inherited 2/3 of the WCE, the pieces to make the trades to get the Sedins, and Moginly and Bure to bring in Morrison and Jovo. The pieces to bring in Luongo were also inherited. Even Benning didn't inherit nothing. He inherited Horvat, Markstom, and Tanev, and pieces from our 2011 team that did return assets. It's a GMs job to set the right direction, and execute. I don't care what they inherited.
2) In the case of Gillis, Zito, etc, they weren't hired to build a new core/rebuild. They were hired because the previous GMs failed to build a competitive team around the core they built and were fired for it. If Gillis and Zito got to build their own core it means they built more losing teams.
3) Like I said, GMs that build their team preside over losing period and all they have to do is hit a the odd high pick. I get that every team has to rebuild. But GMs like Tallon and Benning built their teams because they got to keep their jobs 7-10 years despite continually losing, and never had a planned rebuild.
