Was Corey Perry more valuable in 2010-11 than Previous Seasons?
By all accounts, Corey Perry had an exceptional season in 2010-11 and this is particularly true down the stretch when he flew by Steven Stamkos for the lead in goals scored and pushed himself into serious contention from the Hart Trophy as the leagues most valuable player. There is no doubt that Perry’s production level surpassed anything he had previously done in his career, but was he truly more valuable to the Ducks than in previous seasons? Let’s look at the numbers.
Based on the raw stats, he has been better in 2010-11 in terms of goal scoring and fairly consistent in terms of collecting assists but despite his increase in goals and points, his +/- hasn’t increased significantly.
Let’s look a little deeper into Perry’s even strength 5v5 statistics.
For those unfamiliar with my terminology, GF20 is Perry’s goals for by team while on the ice per 20 minutes of ice time, GA20 is the same for goals against and GF% is GF20/(GF20+GA20) and represents what percentage of all goals scored while he was on the ice were scored by his team. The TM stats are the same but for his team mates when they are not playing with Perry and the Opp stats are the same but for Perry’s opponents when they are not playing against Perry.
Now, the first observation you may make is that Perry’s GF20 was lower in 2010-11 than in any of the previous season so while Perry produced more offense (goals in particular) in 2010-11 individually, the team produced somewhat less when Perry was on the ice. In other words, Perry’s goal/point production may have come at the cost of his line mates goal/point production. The same thing is true defensively. More goals were scored against Perry while Perry was on the ice than in any previous season.
Now, looking at team mate production when his teammates are not on the ice with Perry we find that they produce slightly fewer goals per 20 minutes (0.876 without Perry vs 0.928 with) but also give up slightly fewer goals too (0.843 without Perry, 0.882 with). What is interesting though is Perry’s line mates this season appear to be better offensive players than in prior seasons as their 2010-11 GF20 was 0.876 vs 0.694 in 2009-10 though they also had a slightly higher GA20 in 2010-11 as well. So from these numbers it seems that overall Perry played with significantly better offensive players in 2010-11 than in prior years and slightly worse defensive players in 2010-11 than in prior years.
As for quality of opposition, the offensive production of Perry’s opponents in 2010-11 was about the same as in 2009-10 while defensively they were slightly better.
So, in summary we can state that when Perry was on the ice in 5v5 even strength situations the Ducks produced less in 2010-11 than they did in 2009-10 and gave up more goals in 2011-10 than they did in 2009-10. Furthermore, overall his line mates appear to have been significantly better offensive players in 2010-11 than in 2009-10 and only slightly worse defensive players while his opposition appears to be similarly skilled offensively and marginally less skilled defensively.
So, what does this all mean? Here are Perry’s offensive and defensive ratings:
With all things considered, despite scoring 50 goals this past season, one could make an argument that 2010-11 was well below his performance during the three previous seasons. It seems that his improved individual numbers may have come at the cost of his team mates and that made him less valuable to the Ducks overall.
