Price succeeded Dennis Erickson, who recommended him for the job. Price never coached under Dennis, but they were good friends, having been high school teammates. I suspect that both had the same philosophy as far as sophisticated passing attacks. I think Dennis might have coached under Jack Elway at some point, and I think Elway was a west coast passing offense guru. The last year he was at WSU, Dennis had Timm Rosenbach and two 1000 yard runners, Steve Broussard and Rich Swinton.
I have a feeling, without researching it, that it was very likely that Price had a very similar philosophy to Dennis.
