What about Dermott though? Can't expect him to play off side for a while at the NHL level. I do think you could see him in the top 4 on his LD side by the time Gardiner is gone though.
Borgman too. Could see him in the NHL as soon as next year as well.
Another good top 4 defenseman is always useful and there's no reason why Dermott couldn't play on his offside if need be
Play the best dudes and worry about handedness later imo
