Spent some time researching the Otters returning production on the backend because I wanted to see where it ranked historically. I have attached a chart here for reference.
Disclaimer:
*This data has some obvious flaws and I’m not pretending it’s perfect or shows any consistent correlation. But I did all the work so I wanted to share with the group if interested.
Of note: The data doesn’t take into account the goalie situation or who started in net during years where GA increased versus decreased. It also doesn’t account for overall production returning. For example: This year, Christian Kyrou returns. For the purposes of this chart, I only counted his GP, Goals, and Assist production from 2021-22 and not any stats from his play in 2019-20. In other words, returning production here is only accounting from the prior year.
*In the attached chart - GA stands for Goals Against that season. GP stands for combined games played on the backend returning that season from the prior year
Key takeaways:
Erie’s 368 GP returning production this year on the backend ranks 2nd best in franchise history - behind only 2014-15 (383 GP returning). Their returning combined goal production on the backend from last year ranks best in franchise history with 36G. Their returning assist production (98A) ranks 2nd best behind only the 2010-2011 team.
When Erie returns over 300 games of production from the year prior, 62.5% of the time their GA goes down that year with an average decrease of 44.6 goals from the year prior.
- In the years their GA did not drop despite returning over 300 GP of production from the year prior (2002-03, 2009-10, 2014-15) - they either lost their starting goalie from the year prior or were coming off an OHL title season/obvious rebuild.
When Erie returns more production than they did from the prior season (which happened 12 times in the 24 seasons I charted), their GA goes down 66.6% of the time with an average drop of 59 GA per year.
- The lone exceptions where the GA average went up despite better returning production from the year prior were 2002-2003, 2009-10, 2014-2015, 2018-19. Three of those four years were just touched on in my earlier point. In 2018-19, Murphy returned but the team was still very early stages of the rebuild and trading off players.
- Also noting that in 2014-15, their GA still ranked 6th best in OHL despite an increase in GA from the year prior. Still a great GA season.
Despite Erie’s poor performance last year, only returning 79 GP on the backend from 2019-20, and having the 2nd worst team SV% in the league - they ranked 14th in GA.
Overall, the data suggests their GA should decrease this season on average. The main outlier in the data here is 2018-2019. The other 3 seasons where GA didn’t decrease despite returning more production were 2002-03 (clear rebuild/coming off OHL title), 2009-10 and 2014-15 (replacing legit starts in Janus/Dansk). But in 2009-2010, they were still near average in GA while in 2014-15, they ranked 6th in the OHL in GA. Overall this 2022-23 has a chance to be better in net and they return 368 GP on the backend compared to 237 GP returning in 2018-2019 (which ranks 16th out of 24 seasons in Otters history - so not great). That 2018-19 defense the following year, in 2019-20, when they were older and better, returned 324 GP and dropped their GA by 64 which ranked 11th in the OHL. Pretty good for a borderline playoff team.
The 13 best seasons Erie has had with returning production led to a decrease GA in 10 of those 13 seasons, or 77% of the time. The outliers there are still those same seasons talked about earlier - 2002-03, 2009-10, and 2014-15. Let me add that 2009-10 and 2014-15 groups were also coming off major production drops the two years prior, making it almost a guarantee their GA would increase to some degree because hard to get better than what they had done the year before
