An OHL champion goalie is pretty good. I feel like you do this knowing Mesar is coming, elminating the need of adding a top OA forward. D I think there will be some part-swapping; I like the depth and the pieces, I just don't like how some of them fit together.
Stay at home D are generally not that hard to get, and if we move a body out (Motew for me), in dampens the impact on the trade chest.
I also like the goaltending depth with this; if one goes down in the playoffs theoretically the other can play (we saw Parsons do it against London last year), with Vandenberg as a back up in those cases. It also means we aren't running Parsons ragged through the season and pinning our hopes on him in the playoffs, worn out. I don't see it as tandem, I see a 1A/1C type thing. Parsons is an ok starter, Constani is a legit proven winning starter, both of them should be able to carry their own weight and then some. Parsons maybe starts more than a normal backup, but Constantini carries the majority (60-40ish), leaving both of them more likely to be healthy and rested for the playoffs.
The pieces in front of the goalie still have a lot of work to do in learning how to play together as a team though.
