Sorry, misremembered.
While I won’t get too deep into it, despite injuries and lockouts robbing hockey of a lot of Crosby’s brilliance during his best years, when he was on the ice he hit an offensive level that nobody else has touched in the NHL’s Somewhat Better Data Era. The five best four-year windows by way of GF/60 all belong to Sid and he peaked with a four year run between 2009-13 in which Pittsburgh scored 4.5 GF/60 with him on the ice. In his age 20/21 seasons, by the way, the Penguins put up 3.3 GF/60 with him on the ice.
McDavid’s been outrageously, outrageously good to this point in his career – the Oilers have scored about 3.5 GF/60 with him on the ice at 5-on-5 which is phenomenally good. Imagine if they got 30 percent more though. For example, if McDavid’s playing 22 hours of 5-on-5 ice time and he blows up like Crosby did in this window, you’re talking about another 7 or 8 points in the standings per year. The easiest way for Edmonton to improve is to get more out of what they already have.
It’s hard to say if this is really possible – maybe Crosby just found a level McDavid will never hit – but if it is possible, it’s a gain that the Oilers should desperately be chasing.
