I'm not so sure he has attitude issues. I do believe this team has the center depth to succeed without him. I'm not sure it has the depth however to succeed without Boone and Horton plus Johansen. What the CBJ needs is scoring depth on the wings.
What his board needs is more of The Godfather references. I think one side or the other should make a horsehead offer.
With the current configuration, I think we have more skill on the wings than last season. We switched Umberger and Hartnell. That probably ends up being about a wash offensively. Then dropped MacKenzie for Chaput - that one is probably also a wash. Wennberg, Rychel, and Dano (I think) are more skilled than Comeau and Skille. Last year's Horton wasn't the Horton we fans thought he could be due to injuries. Gaborik didn't play a whole lot.
My opinion, the CBJ will be fine whether Johansen suits up or not. Bob and McElhinney have looked good this preseason, the defense is more or less intact from last year, the guys from the AHL were all schooled in CBJ hockey. Everyone is on the same page. Do they have a true "#1 line"? No, but they didn't have one last year either.
