As a whole, the refs do not favor specific teams. They do typically favor the losing team, however.
Yeah I have to say the recent interview with Tim Peel was rather interesting in that regard. It may have been the first time an sports official has gone on the record and basically stated that the league encourages bad calls in order to enforce an agenda and keep a game competitive.
Here is a section from that article:
"Peel called diving on the Anaheim Ducks defenseman (Sami Vatanen) in one of the single worst calls of the NHL season. It sent Bruce Boudreau into hysterics, and rightfully so.
But Peel knows it was a bad call, to the point where he skated up to the Ducks bench and apologized the next time he officiated an Anaheim game. So why make it? Well, because the NHL wanted a crackdown on diving, and with that mandate, he felt compelled to make that call.
In talking to Peel, you start to see a pattern: The NHL asks its officials to manage the game a certain way, and they have to do it. The Alex Ovechkin penalty in the previous night’s game in Washington? (The Ehrhoff hit)
Peel admits it was a call he wouldn’t have made in a 1-1 game, and wouldn’t have made without knowing that the NHL wants this penalty for the sake of "game management," in order to ensure a 4-0 game between two rivals doesn’t get out of hand. Peel said he went over to Barry Trotz after the call, explained it, and the coach, having seen this episode before, said he understood."

Speaking of officials, I would love to see the league purchase the FoxTrax puck patent from FOX. It's not like it does FOX any good since they no longer have anything at all to do with broadcasting hockey? Then put the tech to good use...no not the revival of glow pucks but an simple chip in the exact center of the puck combined with a sensor bar at the top of the net at 1.5 inches in. The center of the puck passes under the bar and you now know the puck was 100% in the net. No need for officials to try to guess if there was any white visible, or if the goalies glove flashed inside the net, or if the puck squirted in under a mass of humanity before it was pulled out.
And speaking of tech can we also maybe upgrade the ref's whistles? In addition to sound how about making them send a signal to the replay booth so you would have the exact timestamp of when an play stops so that video replay can be frozen at that exact moment without having to just guess approx when the whistle blew, or saying that a whistle blew when the puck had already gone over the line?
It's minor stuff, but the more of the element of human judgement you can remove from the equation the better IMHO...
