Breaking down Corsi performance vs. expectation by defense groups.

Same as below, now looking at blocking shots and hitting the net.

Comparison of some offense measures among different types of defensemen; Google interactive charts were kinda buggy when I tried to insert them into a WordPress post, so here I am w/the image file.

Just a revisit to my regression predictions from January 1st, viewable here. Basically, I predicted negative regression for Montreal, Washington, Phoenix, Colorado, Toronto, and Anaheim, and positive regression for Florida and New Jersey.

Once again using Greg Sinclair’s great Super Shot Search site, here’s a comparative GIF of shooting locations for replacement, defensive, balanced, and offensive defensemen.

Similar to the previous post, here are the shot locations of defensive defensemen (top) and replacement defensemen (bottom) over the last 5 years.

Stick tap to Greg Sinclair’s excellent Super Shot Search site for making this chart possible.

This is the last 5 years of shot location data for offensive defensemen (top) and balanced defensemen (bottom). The concentration of shots closer to the net seems a bit stronger for the offensive defensemen, though overall they are pretty close.

The NHL game reports give us individual TOI data, including even-strength, powerplay, and penalty kill TOI back through 2002-03. Using this, we can build some pretty interesting databases with season progressions such as the above. Here, I’ve taken two young players, one (Ilya Kovalchuk) a highly talented, much-needed forward for the early Atlanta Thrashers; the other, Craig Adams, was a late-rounder who chopped his way through the NCAA and up to the NHL, finally getting his first real minutes late in 2002-03. These TOI charts I developed (starting quite awhile ago over at AIH) take a player’s TOI and expresses it as a percentage of the top TOI in those strengths (forwards and defense are split up). Top-liners would be right up against the 100% mark; 2nd liners are more around 80-85%, and so on down. These charts can show very interesting stories related to player production (since production is strongly attached to TOI)…here, we see Craig Adams earn a major role in Carolina’s forward lines in the final 20 games of 2002-03. No surprise, then, that he produced nearly 65% of his shots and other offensive production in those games. Kovalchuk, of course, was just moving into a massive role in Atlanta’s offense (along with Dany Heatley).

This is just one of many things we can do with the mounds of buried data from the pre-BTN Era.

Taking data all the way back to 1997-98, this is the distribution of shift length in the NHL for all skaters. The average was approximately 45 seconds. I’m going to look at shift length more in the future, but this’ll do for now.
