First time I agree with you 100%Which we now have 3 of, plus another D man who isn't great offensively but needs to be sheltered because he isn't great defensively either.
So to answer the question you ignored, who are we playing when we are trying to protect a lead? Krug has never demonstrated an ability to play adequate defense against top 6 players. Neither has Faulk. Neither has Dunn. Neither has Bortz. Dunn and Krug can't kill penalties at an NHL level. Who kills penalties when any of Parayko, Scandella, Faulk or Bortuzzo gets hurt or takes a penalty?
Dunn must be out. Mikkola can eat PK. He has done it finnish league and AHL.
I still View Mikkola is the predict fit with Parayko for d-pair.
Im not sure can Mikkola take needed stop, but if he does we've in out hands Jbo replacement who will play also physical way.
Mikkola just needs his opportunity.
