They have 2 dmen who have broken 70pts more than once in Karlsson and Burns. They have one of the best forwards in the league at deflecting pucks in Pavelski. They have one of the best playmakers the game has ever seen in Thornton. Then they plug in Couture or Hertl or Donskoi and they have a very dangerous unit. Laine and Scheifle are very very good don't get me wrong, but I'm siding with experience here.
This is asking what Powerplay will be better, not which players are better overall.
Anyways, if I where to start a Power Play today the first person I’d pick in the entire league would be Laine(second would be either McDavid or Ovechkin). Now you add Scheifele who also has an amazing shot and who is one of the best slot shot generating Centers in the game, Wheeler who is overall Elite and is as hard as anyone to get off the puck when given space(to make plays), Connor who has an excellent shot with great hands to work in space and Byfuglien to help equalize the right side of the ice with his bomb of a shot it’s not really that hard of a decision.
All that being said San Jose does deserve credit for having the two best scoring D men in the league but they just don’t have the shot qaulity and damage the Jets have on there Powerplay. Both will be Top 10 next season and imo both are Top 5 in the league on paperz
