From what I understand there are different rules within the team for Wheeler, Scheifele, Buff and Little. When those guys are coasting, the other players see that, and it can cause issues within the team. I also understand that Wheeler/Scheifele do not want to play with Laine, which can also cause a divide in the locker room. The leadership group needs to step up fast here, and I think Maurice needs to split up Wheeler and Scheifele for a period of time, to help the locker room.
I seem to recall last year, the Jets went through a bit of a lull around this time of year, and Wheeler picked a fight in practice, which got the guys fired up. Since that moment, the intensity in games really picked up as well. Maybe Wheeler needs to start another fight in practice. Trading for Stone could light fire as well.
