There's no obvious choice on the Leafs. I don't know if Phaneuf is captain material because lets face it, we don't really know how these guys are off the ice. I'm kind of hoping Frattin steps up as a leader in the next few years.
Goose was always a leader in the Sabres room, and at one point I actually thought he should have been the Sabres captain, but there's probably a bunch of folks who wouldn't want a bottom 6 guy to wear it.
I think most fans are regarding him as borderline waiver wire material rather then captain material.
Legwand or Erat for me, they've stuck by this team from the very beginning through thick and thin and anemic. If Weber plays out his contract the next captain will be Colton Scissons though.
