from Red Fisher of the Montreal Gazette,

Shanahan shouldn’t be blaming the referees. Instead, it lies with the blizzard of new rules in this new My NHL 2. Calls made on some nights aren’t called on others, and the biggest reason for it is that refereeing is difficult enough without having all of their calls assessed and often second-guessed on television monitors by a gang of hanging judges in Toronto.
Referees enter every game wearing cuffs - at least in their own minds - and it’s been that way ever since the two-referee system was introduced. Their jobs depend on it. At the very least, their calls dictate how far they’re allowed to work in the playoffs - if at all.
