For the topic, i say easy Ovechkin, just to get scoring chances now is so difficult, you play the best of the best, team have all good zone coverage. In 2017 you can watch many games where top line guys couldnt even get 1 good chance of taking a quality shot, in the 80's it was too open you had at least a couple of good scoring chance per game minimum. Goaltending was weak and you had much more time to make something with the puck before having a guy in your face. They calculated that guys can skate from blue line to blue line more than 1 second faster in since 1997! So it might be a good 2 to 3 seconds compare to 1982! That means most of the time a guy had an extra 1-2 seconds to make a play, thats enormous.
The ultime test is to look at the 92 goals and put them in 3 categories, the sure goals still now, the maybe goals and the NO WAY goals but even then there is alot of Ovy's shots that didnt end up in goals in 2008 that would of went in in the beginning of the 80's for sure.
So for all this, its not even a hard decision to go with Ovy.
