Hurricanes hire Tyler Dellow as Assistant GM

[Jiri Hrdina]

Do you really think that looking at his abilities through the lens of some cherry picked online articles allows you to conclude that "objectively" he probably doesn't help the Hurricanes?

A bunch of stuff. Expected goal percentage on each shot. Number of times a player has a goal percentage shot of X%+ and passes it up or is unable to take it.

There are so many opportunities to use that tracker in their jerseys (and I assume there's one in the puck) to learn about optimal positioning. I'm talking about this thing:



Instead they waste the technology to show the TV audience who's on the ice on a PP or how fast they're skating.

I wish they'd give us everything and people could create their own multivariate analyses to see what's predictive and what's useless.

In baseball you can get spin rate, horizontal break, vertical break, how often every player swings at pitches in the zone, how often they chase pitches out of the zone, park effects, launch angle, exit velocity, catcher framing, fielding value, even a daily evaluation of how well or poorly an umpire called the game. They had to change the rules because teams got so smart about shifting the positioning of infielders to certain hitters' pull sides. MLB gave us all that with Statcast, which is what I thought NHL Edge was going to be.

I think first we need to stop using baseball as a comparison. They can get all that information because it's done at a snails pace. Hockey is fast. If you want all these stats during the game, you wont be watching the game, your face will be glued to your phone.

They can add certain things during the game sure, and I agree with the xGF from shot locations and so forth, but its so fast you will most of the actions.

Oh, I don't want them showing all that on TV. Just the score, shots, and time remaining is good enough for me. When the game is on I just want to watch it.

But after the game, I want to be able to get at all that stuff.

Oh ok that makes sense. I agree.

The issue is all the free services right now, everyone has their preferred place to get info from. Natural statrick, money puck etc.

If it's centralized and tracked by the NHL you get better information. Bettman is too old school.

the tracker can tell you where on the ice the player is, but it can't determine the quality of the shot that he did or didn't take.

Baseball is static. The pitcher throws a pitch from the same spot every time, when he's ready. The batter will or will not swing.

In hockey, every single shot/play is different, and there is more or less available time to pull it off. They are also shooting with a stick, so there is the added variable of where on the blade the puck was, was it on edge, etc.

Baseball is highly conducive to statistical analysis, because every play is static, measurable, and repeated. Hockey is the complete opposite.

It makes it more challenging, not impossible. It seems a bit defeatist to throw our hands up and say hockey is chaotic, which I don't think it is - it's possible to read and anticipate the play.

The release point of a pitch is a variable as is the type of pitch, the count, the score, base/out situation, the park. Swings can vary, stances can vary depending on the count. Where on the bat the ball is hit is a variable. It does lend itself well to statistical analysis as instead of calling it static, I'd call it a series of trials. It's the only sport where you can't waste time to win a game you're leading. You have no choice but to try to get the other team out.

I wish the NHL would release the positioning data as it could lend to interesting projects about optimizing defensive structure. If the data is recorded often enough, you can use the dx/dt and dy/dt to calculate velocity as well (not simply speed) which I suspect is at least somewhat illustrative and predictive of goal creation and prevention.
