The ice time is being manipulated based on Matthews not being as effective on the PP as OV. It’s a bit silly to even have to point out how ridiculously flawed and silly the stat is.
Scoring environment adjustments are great, but at least there is merit to the ‘adjustment’.
Matthews actually is more effective. The point is brought up because of the huge discrepancy in powerplay time between the seasons being compared.
Ovie 07/08: 2.78PPG/60, 4.82PPP/60
Matthews 23/24: 3.96PPG/60, 6.52PPP/60
Ovie 07/08: 460:25 PPTOI
Matthews 23/24: 257:44 PPTOI
To further contextualize this, Matthews has 17 powerplay goals this season, 5 behind Ovie’s 07/08 season, in only 56% of the powerplay time Ovie had.
By the numbers it seems pretty clear cut honestly that this is a bigger factor in their totals than any era adjustment for league scoring level would be.
