No problem being called a dinosaur. We're getting further into the Cretaceous Period but we're not extinct yet.
Grieg absolutely deserved to get throttled. Reilly can't come in with a stick to the head: there shouldn't be any stickwork involved.
It's pretty funny that total p***y-ass NBA players have been upset recently when guys on the other team drop a windmill breakaway dunk with under 30 seconds left in a blowout yet so many posters on a hockey board think it is totally fine for someone to blast a slapshot from 10 feet out on an open net. This has always been an unwritten rule.
What that tells me is that it isn't so much a dinosaur thing but rather the impact of watching the turn-the-other-cheek Kings of the last ~10 or so years. Grieg can go ahead and do whatever he wants in that situation but he should expect to catch shit for it. The only problem here is that Reilly doesn't know how to properly dish out that punishment.
