You touched on it but in 2009 he started over half of Atlanta's games and put up a .915 SV%. I don't think it's fair to look at a few stretches where he played consecutive games and then use that small sample size to decide that he's incapable of being a starting goalie. If anything, I'd say his ability to be a starting goalie is unknown. What stretches are you referring to where Hedberg played multiple games?
I was basing it more on his career to this point. His games played are: 9, 66, 41, 21, 19, 21, 36, 33, 47, 34, 27. He couldn't clinch a starting spot, and I feel like there must be a reason. For example, he was the starter that year with 66 starts. The back up was JS Aubin, who was awful that year (as was the entire Penguins team). The next year, Sebastien Caron came in and pushed him out of the spot. Then he backed up Dan Cloutier in Vancouver, Marty Turco in Dallas, and Kari Lehtonen in Atlanta. That 2009 season, he was the starter over Ondrej Pavelec as Pavelec eased into the starting role. It just looks to me like he's found his niche.
As for the stretches, I was referring to when Marty first got hurt in October against LA. Moose took over and was very, very strong, but seemed to slow down as we got into late October, early November. He got some time off when Marty returned and then came back with a shutout. Then he was sort of a mixed bag... great games and poor games mixed together as Marty was struggling in December. When he and Marty got into a rhythm at the end of the season, Moose was outstanding. I don't trust any of our prospects to be able to handle half a season right off the bat. Even if Moose could do 60 games hypothetically, I wouldn't want to see 22 games of Kinkaid or Frazee with no safety net. I think Marty and Moose make a pretty perfect combination.
