So PPP posted an article about these defensemen some time ago, check it out
here.
Reading it made me even more interested in the Borgman signing seeing as he was the SHL's champion HV71's leading defense scorer in the playoffs. Usually, younger guys/rookies aren't relied upon that heavily, especially in the playoffs. So it means that he earned the minutes due to his play for the top SHL team...
For comparison's sake, Liljegren is going to a much weaker team (that wasn't relegated according to EP) and should hopefully be getting more minutes due to the team's lack of strength but also because he has more experience against SHL competition. This will be the 3rd professional SHL season for this young grey beard.
Speaking of experience, Rosen has been playing against men since he was 21 so he should be better physically equipped for the AHL. There are concussion issues to worry about though. Nevertheless, the Marlies defense should consist of
Dermott (LHD),
Nielsen (LHD),
Rosen (LHD),
Borgman (LHD),
Valiev (LHD),
Holl (RHD), and
LoVerde (RHD).
That's a lot of depth on the left side if the third pairing guy was actually the SHL's leading defense scorer...
