Why are fancy stats so controversial?- Since the announcement by the Oilers that they hired stats guru Tyler Dellow last week, the reaction to the hiring has hit a boiling point. On Saturday Jason Strudwick wrote a post on the topic at Oilers Nation. Yesterday, Derek Van Diest made a now infamous appearance on the morning show on TSN1260 which spawned reaction from Johnathan Willis at the Cult of Hockey and Ryan Batty at the Copper & Blue. This morning Dustin Nielsen focussed on the topic on the morning show on TSN1260. It could be due to the lack of Oilers related news in the middle of August, but the amount of anger flowing through the City of Champions between the fancy stats crowd and the traditionalists is almost overwhelming. Since all the new stats track (from the point of view of the average hockey fan) is puck possession, why are fancy stats so controversial?
