There's jumping the gun, and then there's what the Toronto Star apparently did on Tuesday morning.
According to Chris Creamer's Sportslogos.net, the Star ran a graphic on Tuesday morning calling the Canucks the Stanley Cup champions, despite their loss to the Bruins in Game 6.
The headline read "Canucks Bring Home the Cup," and it featured a large photo of forward Alexandre Burrows hugging Roberto Luongo.
