I think it will be something along these lines...
Lock
Patrick
Two of Morin/Sanheim/Hagg/Myers (really not sure which ones, but I would be willing to bet that two of them are in)
Great chance but may not make it out camp
Lidblom
One more of the four mentioned above
Not likely unless the blow everyone out of the water
Rubstov
Ratcliffe
Frost
The final one remaining of the four defenders
I don't really think there are even any other guys in contention unless I'm missing someone. I doubt Rubstov, Ratcliffe, or Frost make it out of camp, but if they come in and rip it up I think they'll get a serious look. Two of the four big defensemen should be on the team, but I'm not sure if they really want to roll with three rookies on the backend, and certainly not four (not even sure they have the room for that unless they are sending AMac and Manning down and benching one of the other three). Patrick I think is in unless he really underwhelms or gets hurt again. I think Lindblom is close to a lock but they may start him out in the AHL just to get him acquainted with the NA game.
