8 pm my ass, it'll start by 8:15 if we're lucky, closer to 8:20. It's NBC- they must squeeze in as many commercial breaks once people tune in at 8 for the game but before the puck drops when they'll be limited by the game rules for tv timeouts.
8:01 3 minute game discussion/interview (a long one to draw the viewers in)
8:04 4 minute commercial break
8:08 2 minute game discussion/interview
8:10 4 minute commercial break
8:14 1 minute game discussion/interview
8:15 2 minute commercial break
8:17 Puck drop
6 minutes of discussion for 10 minutes commercials- sounds about right.
That's my guess.
