Good point. Also who gets the credit? The player or the coach or is it really just a combination of multiple factors? In SBW's case he had the best team in the comp behind him and he was a known loose cannon - obviously a coach is going to structure the team so his talents can be exploited.
On that note, looks like everyone is getting (imo: a bit too) excited about Haas (and also Ponga but that's another thing)

No doubt he is a great player but are the Broncos putting everything into him because that's all they've got right now? More importantly will he manage to keep his intensity up year after year?
