I can't really present you with facts, this is just based on my 10+ years watching hockey. Anecdotal evidence. I believe what I see with my eyes. And what I see time and time again is refs ignoring calls, calling others, in order to control the flow of the game / appease coaches.
How many times has a ref missed a penalty call, gotten mouthed off at by a coach, then suddenly there is a make-up call?
These guys don't call the game close to honest, they let shit go all the time when they feel like it
