To me, and it's why I love Lindgren, he'll constantly punch above his weight class every shift and he's actually good at it. He certainly leverages whatever size he does have because he has that tenacity. But Lindgren's game is polar opposite to Lundkvist, we all know that.
I have 0 issue with undersized defensemen, but if you're not fast, not physical, not clearly more mobile than your larger counterparts but apparently have a great shot (which I rarely saw, maybe I missed some) - that's a tough case for an undersized guy. (in my opinion, that's my eye test with no fancy charts and I'm getting older so maybe my eyesight is going too lol)
In saying all that, I was actually hoping we kept Lundkvist because he's still young and I think there's more than meets the eye right now. But our return for him has softened the blow for me
