Well then I'd just switch the roles Holzer and MacWilliam were in then, depending on what it is. Granberg should stay in the AHL as the top pairing defenseman so he can play quality minutes as a top 3 defenseman. I feel he's almost a carbon copy of Korbinian Holzer from 4 years ago when Holzer was 21 and everyone thought he was ready. Personally I thought he was too, but then they rushed him and he looked terrible. I'd rather see 1 good year on the top pairing as the top AHL defenseman (or even like a good half year) before I see Granberg in the NHL. Besides, with Holzer and MacWilliam, we don't have to rush him into the NHL until at least until next season.
Korby wasn't rushed. He didn't play significant minutes in he NHL until he was 24. That was the problem. He played significant minutes in the top four, including top pair minutes. He has a bottom pairing skill set and should have been given sheltered minutes there. He was forced into a situation where he was destined to fail.
I'm not disagreeing that we shouldn't rush Granberg. He should however get every opportunity to make the bottom pairing in camp if warranted.
