Forbes said he and Rodell watch every video review in the league and then discuss the aspects of the call.
"Matt's a huge help. He takes a lot of pressure off of me, so in situations like that I can take my time and be sure," Forbes said. "Every morning, we sit down together and go through the challenges from the night before and discuss pretty much every situation. We'll even be sitting at home on an off night and we're both watching games, and he'll text or call and say, 'Turn to the Calgary game, there's a situation happening there.' We make sure we're on our toes and we're always helping each other out."
On Tuesday's call, Kane also was close to being offside, so that complicated the watch. Forbes said he quickly reviewed Kane's skate and said that it was clearly hovering above the blueline, and that's legal by the league's new standard for offside.
That, in itself, can make the job even more difficult. In the past, a skater had to have his skate on the ice and touching the blueline to remain onside. Now, it can be floating above the blueline. Forbes said it's amazing how good players are at understanding where they are on the ice.
"We watch every entry, and it's incredible to see how good they are this year at knowing where they are," Forbes said. "They're such great athletes and they have such great awareness of their bodies, so you really appreciate that when you're breaking it down frame by frame."
Of course, the entire process gets tougher every year. When Ruff made his call, teams only lost a timeout if they were wrong. Now, league rules put the other team on the power play with a missed challenge. So to make a challenge a minute into a game that was pretty revved up took a little confidence.
