I'll just start with this: Frolunda is going to be disappointed if they think Victor Olofsson is going to replace Johnson. They are very similar players in style, but Johnson is just so much better.
The only interesting thing here is the fact that MODO just lost their best player. So a crappy team just got worse. Wonder if the Leafs will try to get Lindgren moved to a better team, either in the CHL, AHL or SHL.
Because it's not going to end at Olofsson. Emil Pettersson and Gustav Possler may follow him back up to the SHL, or go to North America. That's their top 3 scorers gone. Noah Welsh may retire due to injury, so there goes their best defenseman. Their captain may do the same thing. Carl Grundstrom, the potential 1st round pick, may come over to North America or go up to the SHL. Other older high end players may do the same.
Lindgren will certainly get a lot of playing time, but do you really want him playing on a terrible team in the Swedish 2nd league? At least Pierre Engvall is playing in a solid role on a good team and is learning something. I'd certainly consider bringing him to the CHL, or try to move him to a better team in Sweden.
