You are missing the entire point. Edvinsson is playing under 2 year contract with Frölunda. He's their propert entirely. Any involvement by the Red Wings at this point is problematic.
We've seen former NHL players with better careers than Kronwall get back to Swedish hockey and fail completely. I have nothing against Kronwall, experience as a player is never a bad thing but he has zero experience when it comes to player development. Developing teenagers is something Frölunda does better than any NHL team anyway.
Kronwall has been Detroit's developmental coach for several years now and had a similar function when he was in NA right after retiring. Now that he lives in Sweden where many of the Redwing's prospects are, he has been very active in helping our prospects develop there.
Kronwall is highly respected in Sweden not only by Frolunda's staff but also by the national team management. He was even asked to advise for the Swedish national team coaching staff.
As mentioned in previous articles, he has been hands on in terms of monitoring, giving postgame feedback, improving their weaknesses, and even scheduling post game training sessions in Sweden for Detroit's Redwings prospects.
Kronvall is not the sole reason many of our prospects have improved this year in Sweden but even our prospects in interviews point out that he has played a major factor in their improvement this year. Considering that 4 of the top U21 players in the SHL statistically are Redwings prospects, this demonstrates what having a knowledgeable former All Star veteran can do for his organization in helping develop them.
The Detroit Redwings also gets Kronwall's direct feedback and recommendation on whether a player is ready to move on to the NHL and he is most likely directly responsible for getting a promising prospect like Wallinder to move to Rogle this year where he has flourished and has improved by leaps and bounds after somewhat struggling last year.
