Let's face it, they're hockey players, and they're mostly a good group of guys. Even at the lowest barometer, as a group they don't approach the lowly status of many other sports. I won't consider anyone who played here for less than a year, and I didn't start paying daily attention to Hurricanes/hockey until Jan 2000. So, with those disclaimers...
It's probably a tie between Marek Malik and Chad LaRose, for different reasons. Malik because he was the worst player and aggravated me the most of any player, but LaRose due to the length of time that he has taken a roster spot. However, I've somewhat come to terms with LaRose, because his numbers are difficult to argue with and the fact that his coaches have trusted him cannot be ignored. But even with all of that rationality in place in my brain, it certainly didn't pain me to see him get scratched on Thursday.
Sean Hill in his final days was difficult to stomach. Those 225 PIMs in his last two years here came 2 minutes at a time, and they weren't for roughing.
