A big point of contention against AV hockey, especially in the playoffs, is that AV's Rangers tend to grab a lead, and then turtle. Turtle, of course meaning, going into a shell, and allowing a barrage of shot attempts against your goalie. This was highlighted no more in the most recent Rangers vs Ottawa playoff series in game 5. Jimmy Vesey would give the Rangers a 4-3 lead in the third period. After that, the Rangers would go no to be out-attempted by Ottawa 22-2, and lose in overtime.
Score-effects are a very real thing, and of course, there are adjustments that exist to take these into account. (Best reading is here from Michah Blake McCurdy). We know that trailing teams get more attempts than the teams that are leading them. It's just one of those hockey things.
With that, it shouldn't be surprising that the Rangers get out-attempted as they do after taking a lead in the third period. However, it does appear often watching these games, that the Rangers suffer from this at a more alarming event because of the way Vigneault chooses to defend his leads.
So, as we should with the things that we can, I set out to discover if the Rangers under Vigneault have been damaged more by these score-effects in the third period of playoff games versus their peers as a result of "AV hockey".
- The data that was used in this analysis was pulled from playoff games from the 2014 playoffs through the 2016 playoffs. This year's playoffs are not included in this data set
- The data was sourced from Corsica.Hockey's public RData files
- The data focuses on:
- All situations of play
- The only data we are using in the analysis are play-by-play events that occur when the team in question has a lead in the third period at any time
- All situations data here is a choice that was honestly made out of ease of use for me. 5v5 only might have been a better play here
- Doesn't include this year's data
- No study conducted on goals or blown leads
- No time on ice, only a games played number
- More that I'm sure I can't think of
With that said, I think most importantly is the high end number. This study features 7787 total shot attempts. Of the 7787 shots, 3051 were taken by the leading team, and 4736 were taken by the trailing team, for a leading team CF% of 39.2%.
There were 24 teams that had a lead in the third period of a playoff game from 2014-2016. Here's how they all shake out:
The Rangers end up as the 10th best team in terms of Relative CF% to the rest of the league (Team CF% minus League CF% not including that team). Of course, the -143 in terms of running differential is not the "sexiest" number in the world, but it comes with the territory of the amount of games played in the sample.
(Flaw: Again, better here would be to have TOI in these situations for each team so we could get a per 60 measure. Oh well.)
For aesthetics, here's a running differential visualization for the Rangers (each team in the study above can be found at this link:
Are we too hard on AV for this specific item? Maybe. It's a league-wide phenomena. Score-effects are very, very, real. That didn't need to be proven again. But, the interesting take away here, at least for me, is that perhaps for this item, I've been a little too hard on AV. I think that this year's post-season would draw the Rangers a little further down that list, and perhaps this is worth re-visiting after compiling those numbers together when the post-season ends. Not there yet, though.
