I think losing Comrie and Preising will hurt Ott, but after signing Emery, there's no doubt who's team it is, so I don't think there will be a goaltending controversy in Sens land.
For whatever reason, the Sens have always had the Habs number, right down to the first time they played ( fall after the Habs won the Cup in '93). I don't dislike them as I do the Leafs or Bruins, and have even rooted for them on occasion ( like last years playoffs).
It's going to be a good season, and I'm looking forward to it.
