I think you guys are overlooking the apparent difficulty in finding good complementary forwards.
We signed like 5 of these bargain basement guys last year and none of them were good enough. Thornton, Simmonds, Vesey, GForce (though he was good enough that I'd like to see him back), Boyd, and whoever else I'm forgetting.
Kerf is a lot better than these guys. Maybe the market this offseason yields more comparable players willing to play for less and provide roughly the same results, but I'm skeptical. We need guys who are capable, who can skate fast, who have some offensive ability, and can play both ends of the ice. Kerf is better than everyone is giving him credit for here, and we're going to be in tough to replace him and Hyman from the castoff pile - another reason why I'd be bummed to see McCann plucked.
