I don't recall ever calling Trouba the worst defenseman on the team?
I have an issue with crossing things off without trying them. Maybe Trouba/DeAngelo/Fox will work on the left side. Maybe they won't. But it is certainly worth a week, two weeks, or a month to see if it does.
I get that, but I think it has some limits too.
ADA's defense, when he played the left side, was even worse than it is on the right side --- and that's saying something.
At some point, we have to accept what players are and what they aren't. Sure, we could force the issue and try to salvage something from moving things around. Or we can really focus on solving the problem and getting the right pieces, for the right positions.
On any given day, we want to take a look at Kravtsov at center, Lafreniere at center, ADA on the left side, Kakko at center, etc. etc.
I think the key is focusing on the development of players in their proper positions.
Player development is tricky enough while balancing confidence, with momentum, with putting players in positions to enjoy the rewards of their efforts, while minimzing how you expose them.
On the one hand we talk about how important player development is, on the other hand we want to get experimental with kids who play the positions they play for a reason.
At the end of the day, we've got what we've got and we'll need to plug in the holes that exist. And devoting time, energy and resources to trying to make a square pegs fit into round holes carries significantly more risk of giving us a depreciated value than of solving the actual problem.
