16 year olds rarely make the team (Gretzky, Lindros, Spezza, Bouwmeester, Crosby are the only ones who ever have), and I'd be shocked if Esposito even got remotely close to making it. Right now it's looking something like this:
in goal:
Price
Dubnyk
Ellis has a very outside chance if he plays great or if one of Price or Dubnyk get hurt or really suck before Christmas.
defense:
Barker (is he back from Chicago yet? in any case, he'll be at the WJs, even if he's still with the Blackhawks, which is unlikely)
Fistric
Bourdon
Staal
Parent
two of Rogers, Mikkelson, Jackson, and anyone who has a great start to the year
up front:
Chipchura
Bolland
Brule (who should be back with the Giants after he recovers from his broken sternum)
Pouliot
McCardle
Boyd
Latendresse
Wolski (if the Avs release him, which I expect they will if they haven't sent him back to junior)
then 5 more of these guys (in what I think is the approximate order of their likelihood of making it): Little, Comeau (I really think he should be on this team), Bourret, O'Marra, Bass (I bet Sutter loves this guy and he fills the 4th line centre spot nicely), Chucko, Bertram.
Some other guys who could make a case for themselves if they have good starts to the season include Setoguchi, McGrath, Cogliano, Pyatt, Toews, and probably a few others I've missed.
This is all subject to change because of injuries and how guys start the season, and a couple checker/grinder types probably need to be added, but the team should look something like that. Whole lot of 87s in that group.
