Being a fan of Fasths's former team, AIK, I am both biased and somewhat in the loop on his previous performance. AIK has been a grinding team with few truly talented players since being promoted so the SEL. Fasth carried us through those seasons, because simply put, the team was not good enough to get a win with whatever backup we had in net. If he let in 2 goals, we were unlikely to get a win. He did not play as much as a nr 1 in the NHL, but his workload per game was huge. He had to bail us out more often than not, making big saves.
Also, despite having fewer games per season than the NHL, there are regular national team tournaments during the season, where Fasth saw action. Look at the 11-12 season for instance. He played 46 regular season games, another 12 playoff games, and 23 national team games. That's 81 games in one season. The season before he had 68 games.
The regular season starts in mid-September, and the semifinals (where AIK were eliminated both years) end in early-April. On average, Fasth played two games a week, on a team he had to consistently bail out, for the entire season. He is now on a Ducks team that is playing well, and he does not see the 30+ shots he saw most night in the SEL, plus this is a shortened season.
In conclusion, I see no reason why he could not sustain this level of play, at least this season.
