It's not just size, you can be small if you're fast. He's not fast enough. It doesn't matter how well he moves the puck if 99% of the league can win most puck battles against you.
Actually it does. You haven't considered that one reason our current defensive squad looks so terrible is because they can't move the puck very well? We get stuck in our own zone because Lashoff, Kindl, Quincey, even Dekeyser, Ericsson and to some extent Kronwall struggle to cleanly start breakouts. It doesn't matter how good you are at winning puck battles if when you win the puck you do nothing constructive with it.
Fingers crossed Holland has some big plans because if we go into next season with Kindl and Lashoff still around I'll be a bit upset that we let our best puck-moving d-man leave for Russia.
So you want to trade one problem for another. I'd rather fix the issue.
