You’re completely wrong here, Laine played with Scheifele and Connor for most of 2019-20. A major reason why that happened was Little got hit in the head with a puck in November 4th 2019, it broke his eardrum and that likely ended his NHL career. Little played 7 games in 2019-20 and he hasn’t played since.
Here are the 5v5 ice times for 2019-20, you can see he played on that line ~760 minutes vs ~270 minutes. And when he didn’t play with Scheifele and Connor he was forced to play with talentless bums like Wheeler and Ehlers.
Patrik Laine - Teammates - On Ice - Natural Stat Trick
Humorously, people talk about Laine scoring 35 assists (20 5v5) in 2019-20, like he had some magical transformation to a playmaker when he was playing with goal machines Connor and Scheifele.
Also, Laine only played part of his first season with Scheifele and Ehlers was a big part of his season that year (and probably the play driver he needs the most).
In his second season Laine played with Little and then Stasny in the last third of the season, pretty much always with Ehlers on wing. There was also ~10 game stint with Wheeler and Conner, Laine never played on a line with Scheifele in 2017-18. He even publicly bitched about it.
Then in 2018-19 he did play with Little, first with Connor and then with Roslovic. Admittedly having Roslovic with them was pretty brutal but that’s because Laine at least needs someone like Ehlers to carry his ass up the ice.
Laine is a shooter who, when handled correctly, can be productive, particularly on the power play. He isn’t an elite forward who should get an enormous contract though, he doesn’t even perform that well with good offensive players unless they mesh incredibly well and carry the play for him.
My guess is one of the reason’s Chevy dumped Laine is he got to play with his precious Scheifele on the top line last season and didn’t show much of anything special. And still wants a ton of money. (And Ehlers is likely better off not having to drag Laine’s ass up the ice, he’s having his most productive season ever.)
