Unless Rask really lights it up in camp and Lindholm fails to impress, I can't see how Rask makes the squad (barring injuries)
7 top 9 forwards are givens: Tlusty, Staal, Semin, Skinner, Staal, Ruutu, Dwyer.
1 forward is very likely: Lindholm
Westgarth is probably the 13th forward
So unless there is a trade, that leaves 1 top 9 spot and 3 fourth line spot to be fought out between:
Dalpe (waiver eligible), Boychuk (waiver eligible), Rask, Welsh (1 way deal), Bowman (1 way deal), Nash (waiver eligible?), Sutter (waiver eligible) , Palushaj (waiver status?), and Jared Staal.
Since Rask would not be exposed to waivers to go to Charlotte and does not have a 1 way deal, he would have to significantly outperform all the other guys fighting for that 1 top 9 spot (as he won't be on the 4th line) in order to make the squad.
It may happen, but I don't think it's as likely as some seem to imply.
