Few things as to why I value AHL higher than every men league in Europe :
- Small ice surface
- More physical (main argument)
- They have a vet maximum rule, but those vets could probably play on a 4th NHL line and not look so bad
- Everybody is fighting for an NHL spot so they play at their best
I think if you put let's say a Liiga team on a small ice surface, I think they would struggle with the physicality of the AHL. If you put an AHL team on a bigger ice surface, they might have a hard time with the speed of their game. But since hockey is harder on a smaller ice rink, I put the AHL above Liiga. SHL is pretty close to AHL tho, could probably ranked them 3A and 3B.
No, the top Euro leagues are better. The AHL is, first and foremost, a developmental league where winning is secondary to player development. Ice time allocation doesn't always reflect current merit.
In general terms, a reasonable comparison is double-A vs triple-A baseball. Even though it’s lower level, clubs prefer to have their top prospects play AA. AAA is commonly for topped out vets.
