They can't do anything without ticking people off; just the fact that they exist makes people uncomfortable. Who might I be referencing? Nickelback, of course! As Canadian as whatever passes for Canadian bacon on pizza, Nickelback has to somehow get lumped in with the NHL because that's what they think people want. When you have an entire city begging the League to not book them as the entertainment for the NHL's annual Face Off Weekend, that is not an endorsement for them to be entertainment for anything having to do with hockey.
So, well, why NOT book them as the musical guest for the 2012 NHL Awards? Stands to reason. For an awards show that booked Chaka Khan as their first musical guest (I'm sure that there's an "I'm Every Woman" joke in there somewhere) and who thinks that Jay Mohr is an appropriate host even though he said that he hated hockey, this move makes perfect sense.
I'll go out on a limb and assume that this is just a sign that neither Jon Hamm nor David Boreanaz will be hosting any time soon. Much like they do with musical guests, why not bypass legit famous puckheads for the hosting gig? I mean, who wants to see Jon Hamm and Henrik Lundqvist together on stage at the same time anyway?
