I find the analytics crowd for hockey endlessly annoying and sometimes irrelevant. Wow, a good team has good analytics, tell me more. Oh, a bad team has bad analytics, tell me more. Wow, such helpful insight. Something tells me a lot of the stats guru's never actually played on competitive sports teams and are lacking in the overall understanding of team building, human resources, etc.
The analytics and sabermetrics crowds seem to forget that the A's didn't win the world series, many teams use analytics and fail and there is more to sports than just isolating numbers for players. The whole human element is important too. We aren't robots. There is nothing more true about human beings than change. Nothing is static and these players are always changing. But endless analytics pigeonhole players as static variables forever destined to be the player the numbers say they are....
If you have ever met or been friends with NHL players in real life (or professional athletes) where you can have can have candid conversations with them, you realize they are people and life bleeds over into their profession. Just like all of us, and this can have an impact on them. Stats give you a piece of information, but it is just a single piece of information. It can help tell a story but you should not use the stats to tell the story. Or you will get it wrong.
