Probably not a penalty shot, but I suggest you have succumbed to Shoalts' hyperbole on the call. NHL ref's have been instructed for some time to call a penalty anytime a defender lays his stick on the hands of someone with the puck. Hunwick did that. Or at least got close enough to Chimera's hands to justify the call. Whether he was free-and-clear enough to justify a PS, that's debatable. But "the worst" call? or "a most egregious injustice" according to Shoalts?  That's a bit over the top. 
Also, Andersen could always have stopped the PS...  Shootout stats suggest goals are scored on about one-third of all attempts Not sure if penalty shots have a higher success, no real reason to think they should be. So odds were in Andersen's favour. Ultimately it didn't really matter.
