Actually. Im not sure i totally agree with that statement. Take a player like Anton Strålman(probably totally unknown here). He is a top 2 defenseman on a pretty ok team in allsvenskan(tier 2 mens hockey). Receiving tons of ice time every game. He is on eight place in scoring among d-men in the whole league with 7 goals and 4 assists in 27 games.
Thats pretty good. He opted out last year to the draft(skövde played tier 3 hockey), but there were some NHL-scouts who were really impressed. He is basically a copy of Oscar Hedman, except he is a bit better at this point offensively but weaker defensively(still very good). Elias Granath is also a regular on a really good team(Leksand) who will have a chance of reaching SEL again. These two are maybe the two weakest d-men. So im not sure i agree. But its the smaller rinks now too. This is based on the bigger rinks
