That's one thing I've noticed a lot lately. The puck takes forever to drop, and inevitably one or both face-off men get tossed.
Now, maybe the problem with the puck drop is that the linesman is waiting for all the players to settle in.
However, it seems that the longer it takes to drop the puck, the more guys tend to get out of their spots, do some stickwork, and bam, someone gets tossed.
How about if they get the guys on the ice, the face-off men float up, and the puck gets dropped right away? Enough waiting around...
