I find it very interesting that Koivu has so many shots when playing back in Finland. After 3 games he's averaging 5.33 SOG/game. In the NHL for his career he's averaged 2.47 and his highest shooting season he averaged 3.075.
It gets him playing and keeps him in North America I would guess. There's not very many other options around here. If you don't want to head over to Europe (and I'd imagine many North American players don't want to) and you want to keep playing, the ECHL might be the highest level league you can join. The AHL has strict limitations for NHLers playing in it, and for the most part they're full up.
