I can see Reinbacher,or Mailloux,making the teapot of camp next season, but definitely not both. There's no way we insert two rookie RHDs to start next season!
We start the year with Matheson - Carrier, Guhle - Hutson and one of Xhekaj, or Struble, on a pairing with one of Reinbacher, or Mailloux.
By Christmas, the RHD not called at the start of the season should get the nod to step up to the NHL.
By the deadline, one of Matheson or Xhekaj get traded, depending on what positions we filled in the offseason and on what either player can garner in trade.
I'd actually really want to see pairing of Xhekaj-Mailloux as a 3rd pairing to start next season. I think the two can have good chemistry together.
With another 25-40 games in Laval, Reinbacher should be ready to step up to the NHL alongside Hutson and he couldplay a safer defensive game to start off, with less expectations and pressure to perform as an all-around D right from the get-go.
