I could accept Matheson as a third pairing D if we had 4 guys better than him too. Personally, I think that would require us finding and playing AT LEAST two new top-4 d-men, EVEN IF one chooses to consider Guhle and Carrier as both better than Matheson to play against the top threats of the other team.
But if Matheson's new role just means playing Stuble and Xhekaj 22 minutes each in the top 4, I think our results will slip, not improve.
Now what is the prospect of getting these two new defencemen who will be #3 and #4 (or better)? Are these players available and if so, are we a better team after paying the required cost in trade capital and/or cap space?
