What I got out of this. 31 time champs?!?! What are there 2 teams?
It was mostly in the very early, "primitive" era. In one form or another, the Swiss league existed since 1909.
HC Davos won the championship 8 times from 1961 to now (last in 2015).
They won 23 times from 1926 to 1960. In those days, being in a colder region, like the canton (= state) of Graubünden (=where Davos is) is, was a
significant advantage.
Think of this... Out of 34 seasons from 1926 to 1960, only 3 seasons saw a team from outside Graubünden win the championship. For 31 seasons, the winners were Davos (23), Arosa (7), St Moritz (1).
I hope this helps.
