Your adding in the scrub teams to your average. Good teams dont change coaches 9 times in since 2009. That's the point. Its not the coach its the shitty players.
Lets use a team like the Avs as an example which have good players. They have had 3 coaches since 2009
Ah if you're using it as evidence the Flyers are a scrub team, then that's fine. Evidence there is a problem, not the reason for the problem. That I agree with.
