To be fair to Murray (should we bother being fair?), its wasn't a headshot this time -- and Murray may even be a victim of circumstance and reputation here. Sundstrom turned from what, if Murray's career is our guide, was very likely an attempt to separate Sundstrom's head from his body. Murray was too slow to react -- that is a general theme for these last few waning years of his career -- and instead drove Sundstrom face-first into the boards.
Murray was once a decent NHL defenseman known for his big hits. These days, he's a bad defenseman who is too slow to legally deliver his trademark big hits.
It's a bit of a problem for Murray and what's left of his career. It's also a problem for the victims caught as collateral damage while Murray and his employers slowly realize it.
