As it stands, only Hayes, Simmonds and Stone are the marquee forwards ahead of Johansson.
Could see Stone extending with Ottawa becoming destitute for a big name player next season. Simmonds staying put since the Flyers are in the hunt, and Hayes maybe onto Boston/Nashville.
That would leave Mojo as the top available forward, and could see a few teams vying for him. Team might want to give a similar package as Nyquist/Dzingel/Zuccarello, but Shero should have the upperhand at that point. Possibly can get a first from a Western Conference team like Winnipeg or Calgary if you tell both teams the best offer gets him.
