My bet as to what happens with the Flames' goaltending this year is this:
Ramo as starter, playing 40 games.
MacDonald as backup, playing 25 games.
Berra as a second backup, playing 17 games.
I believe the Flames will roll with a three goalie rotation - not such a far-fetched notion, considering that as well as Ramo has played in the KHL, he's averaged around 40 starts per year. MacDonald with more experience will get the nod most of the time as backup, but after his outstanding play on the international level, Flames brass will want to get a serious look at Berra, too.
That will leave Brossoit and Ortio in Abbotsford. Ortio had a couple stints with the Heat over the past two year, but sadly his play was attrocious. His play back home in Finland hasn't been anything to inspire hope. Brossoit, on the other hand, has been outstanding in WHL play, both during the regular season and during the playoffs. He will be the starter for the Heat and future starter for the Flames (making an outstanding tandem with Gillies, once he turns pro).
