Honestly, it depends on what you're looking for. Toivonen has Raycroft in front of him, and that alows Boston to give him ample developmental time. If Raycroft falters, or Toivonen performs so well that they'd be willing to trade Rayzor, i'd say he had a pretty decent shot at cracking. However, I don't see it as very likely unless one of those two scenario's play out. Or unless Boston decided to pull a 1a and 1b type scheme, which is unlikely considering both of these guys have what it takes to be a #1 on their own.
Bryzgalov is behind Jean-Sebastian Giguere, and is the only one on this list that has a superstar caliber goaltender on the depth charts ahead of him. I'd say chances are pretty good that he'll either be moved or play backup to Giguere until he hits the open market and possibly decides to leave town. He's also a decent bet to crack the starter position in three years. Also, Gerber in front of him could be a problem but that sub 2.50 goals against average in the AHL is pretty convincing. Breeze might be a victim of depth at the position. Sort of the way a Mika Noronen is a victim of depth in Buffalo.
Pascal Leclaire might be the only thing that keeps him from being able to earn a position in the Columbus organization. He's simply not ready, and I doubt he will be ready to take on a full time role in the NHL in three years. Not saying he's not a great prospect, he's just slow to develop as a great deal of them are. In 3 years I see Leclaire playing his first NHL season as a backup. Conditioning is going to be key for Leclaire in the coming years, and I hope he has what it takes to stick with it. Pretty unlikely he takes the job, in my opinion.
Josh Harding is behind quite a bit of depth in the Wild system. Roloson and Fernandez appear to have it pretty well covered right now and that is going to afford Harding some extra time to develop his game at the AHL level and i'm fairly confident that is where he's going to be in three years time from now. However, three years is a long time and Rolson is getting up there, so i'd not be very shocked if Harding was playing backup for the Wild in three seasons, with perhaps the chance to earn that starting position. However, his first year of professional hockey is going to be crucial to see how he fits into the plans of the Wild, who can afford to wait him out.
Cam Ward is certainly a wildcard. The only goaltender above him on the depth chart right now is Kevin Weekes and one could possibly argue Patrick DesRochers. People i've heard in the 'Canes camp have actually been whispering about the possibility of Ward playing backup next season if Arturs Irbe manages to get out of his contract and sign with another team or retire. However, it's very unlikely that Ward plays for the Hurricanes next season and i'd see him as a very real possibility to get significant playing time with either Lowell of the AHL or Florida of the ECHL. As per Harding, he's going to have to show something in his first professional season if he hopes to be a starter in the next three years. However, it's very unlikely that Carolina tries to rush him with Weekes in the net performing at a high level right now.
Ray Emery has a decent shot in Ottawa if he can somehow reign himself in. He has the reputation as a loose cannon and it suits him well. Despite his hijinx, he's a fantastic goaltending prospect and Ottawa has rewarded him with playing time in each of the past two seasons, which the majority of his time spent in the AHL. He's still very young at only 22 years old, but he already has the inside edge. If Lalime falters in the playoffs this year, i'd expect Emery to be dubbed the goalie of the future for the high powered Sens. Emery has a pretty decent shot, unless the Sens decide to go with more of an established commodity due to the fact that they compete for the cup every season. The strength of these Sens teams may hurt Emery's chances of grabbing a starting position within the next few seasons.
Dave LeNeveu had a pretty rocky season this year with Springfield, but he's still a fantastic prospect. Phoenix has no real franchise goaltender or potential one in the pipes besides LeNeveu and that certainly bodes well for his chances. However, he needs to improve on multiple facets of his game if he hopes to be playing in the NHL on regular basis. Though Springfield wasn't the best team in the AHL, LeNeveu probably should have produced a little better in his debut season if he had any hopes of being the incumbent in Phoenix.
Here is how i'd rank them in list style:
1. Bryzgalov*
2. Toivonen
3. Ward
4. Emery
5. LeClaire
6. Harding
7. LeNeveu
* Not with Current team.
