And Keefe will continue to do that once both the #3/4 defencemen are back on the team but with the added bonus of no longer having to play Klingberg head-to-head against other top-six players.
Rather than freaking out about the player not being able to handle 2nd pairing assignments above his slot, why don't you take a breather and wait for the full group to come back before coming to hasty conclusions.
What you're proposing is to liquidate $4.5M in capspace from the team, replacing him with an AHL player after 13 games in the season.
Seems very reactionary, and emotional. I don't think you've quite come to terms with Kyle being gone and a new guy calling the shots. It's ok to still be hurt about it but you need to sort that out quick.
