That’s interference and that’s instigation. Not sure why the fans are upset about that one
That's my cue to bring up this story: Back in the late 2000s before I left the Bay Area, I put a Canadian satellite dish and was subscribed to Starchoice canadian sat service. One of the perks was when the Sharks play Canadian teams, I got to see Sharks games in HD, but with the opposing team's feed. (This was before all Sharks games were in HD on our local RSN, but Canadian teams had much more games in HD).
Once I watched a Canucks at Sharks game, but the Nucks feed. There was a time when the Nucks D man had the puck behind his own net and wouldn't bring it out. So Sharks fans booed.
But the Nucks announcers said the Sharks fans were booing their team for not sending a forechecker around the net.
The fans and announcers there are a different breed. lol
