He's always been a solid player, but really emerged last year. He obviously won't keep this production up because he is shooting at 23% and Laine at 25%, but he definitely could have a claim to the top 10 in scoring this year.
Shooting percentage is pretty irrelevant given how many "dirty goals" he's scored. From memory he's probably put in half his goals at least just banging home rebounds in the midst of netfront chaos. He's had a few nice shots too, but he's definitely not relying on some kind of unsustainable lucky streak of shooting from anywhere so to speak. I don't think it's an argument that needs to be made right now.
Goal 1 vs Carolina: Two on One turn over, Wheeler passes across to Scheifele on his forehand for a quick shot top right corner.
Goal 2 vs Minnesota: 6on5 Laine the extra man fires a one timer from the blue line, goalie falls down on his butt and Scheifele picks up the rebound goal from just over 5 feet out.
Goal 3 vs Toronto: Scheifele feeds Morrissey for a one timer that gets blocked in the high slot by Marner only to find Scheifele's stick, Scheifele fires it home top left corner before the goalie can react.
Goal 4 vs Dallas: 6on5 Laine fires from the blue line up high off the goalie, Scheifele and Lowry are battling for the rebound and Scheifele puts it home.
Goal 5 vs Washington: Wheeler goes godmode with the puck along the boards and dishes the puck to Scheifele for a quick shot that's stopped, the rebound shoots out towards the corner but Scheifele finds it quickly and bangs it past the goalie.
Goal 6 vs Detroit: 3on2 rush, Laine gets the puck and drives the net, the rebound is banged home by Scheifele.
Goal 7 vs Rangers: Ehlers spins back off the rush and finds Postma trailing for the shot, the goalie can't handle it and Scheifele skates in and bangs home a loose puck in the crease.
Goal 8 vs Dallas: 3on1 break off of a blocked shot in the Jets zone, Ehlers saucers a nice pass over the defensemans stick to Scheifele who fires it in off the side of the goalie sliding across the net.
Goal 9 vs Dallas: PPG, Petan throws the defenseman off by skating down towards the net on his off wing only to feed a quick back hand to Scheifele who blasts it top left corner with Wheeler screening the goalie.
Just thought I'd illustrate the sequences of goals for those who might wonder and obviously don't have the time to watch every single hockey game played across the league.
