Really they "only" need one top 4 D man but they need 2/3 of the top 6 if they want to run our centres as centres.
xxx-McDavid-xxx
xxx-Drai-xxx
Lucic-Nuge-Pulju
Though ideally Lucic goes away and we replace him, so that means 5 new wingers.
Good thing wingers are just soooo easy to find.
Again, we have a lot of players who can play as the 3rd complimentary guy in a top 9. Furthermore, I truly don't believe that we need to have RNH on the 3rd line. One really good forward would make a world of difference. Let's just say we make a move for a guy like Stone (it could be any forward, but I'm using him as an example). Create 2 pairs using McDavid, Draisaitl, RNH and Stone. Players like Chiasson, Puljujarvi, Yamamoto, Kassian, Lucic etc. can fill that 3rd spot depending on your matchup.
What really made me upset was trading away Strome. I know he was struggling to find some offense, but I feel like he was starting to fit in nicely in a 3C role, and with 2 top lines taking pressure off of him next season like that, he could have maybe worked some magic with a rookie like benson and one of yama/pulju.
All that said, I still say our need for a dman in the realm of Klefbom or better is our biggest need. (Preferably right shot)
