If Bergevin really envisioned that though. He'd step in. Therrien is under him.
I honestly believe that for as much good as Bergevin does, he sees the weaknesses in this roster and thinks Therrien is doing a good job with his "system." I think there's less weaknesses than Bergevin probably feels there is, but that's not my job - it's his.
I do think that Bergevin prefers centres (and defenseman). I don't really think he's much for wingers, unless they're obviously a Pacioretty. I think we saw that when he picked up a defenseman and two bottom-6 players that can play wing or centre.
And that's why I think Plekanec, Galchenyuk, Eller, Desharnais, and likely now De La Rose are going nowhere anytime soon.
