Ovechkin is out of sorts. Does anyone know why? (Photo credit: Mitchell Layton)
Semin cooled off, Marcus Johansonn started to heat up, Ovechkin is un-Ovechkin-y, and we saw the Caps get shut out for the first time in almost a year. Quite an up-and-down week. Despite it all, scoring chances are once again preserved for posterity.
I use a specific definition of what I consider a scoring chance based on shot quality data and log everyone who is on the ice at the time using the script from Vic Ferrari. As always, you can find the spreadsheet online.
Coach Boudreau used every line combo imaginable this week (except for the much ballyhooed DJ King-Steckel-Ovechkin line), so I thought we would look at expected scoring chance percentage (SC%). Scoring chance percentage is the amount of scoring chances-for (SCF) that go in the Caps favor when a particular player is on the ice. For example, if a skater is on the ice for 6 scoring chances-for and only 4 against his SC% would be 60% (6 chances for divided by all 10 chances when on ice). If we know how often a player is deployed in the offensive zone, we can calculate their expected scoring chance percentage. Then it is simple subtraction: subtract the actual from the expected and we can see each player’s true efficiency. All numbers are for even strength only.
