From 2002 to 2006. Sweden might have some higher tops, but Belarus overall is better. But not big difference. Notice that i put Sweden at 7th and Belarus as 6th. A small edge to Belarus.
2002 to 2006 then
Ok, 2002 group won U18 WJC with 2001 group, won silver at Hlinka, and there was no U18 WJC that year.
2003 group won bronze at U18 WJC, there was no Hlinka that year.
2004 group won bronze at Hlinka this year
2005 and 2006 didn't play in tournaments. Belarus either, so I wonder, maybe you have some insight into hockey in BLR and there is a golden generation upcoming but the 2002, 2003 and 2004 groups so far have outperformed Finland and Czechia, and Slovakia except for Hlinka this year, but Slovakia 2004 is very top heavy, swedish group is deeper.
So, putting Russia ahead for 2003 and 2004 is understandable. For 2002, no, because Russia is amybe deeper, they are lacking of top prospects from that age.
Putting Slovakia ahead of Sweden for ages from 2002 to 2006 is obviously wrong, because 2002 and 2003 are pretty one-sidedly in advantage to Sweden and 2004 is even at best, while 2005 and 2006 too early to tell
Putting Finland and espescailly Czechia ahead of Sweden is not based on anything.
Putting Belarus ahead of any of classic powerhouses is very bold and demands some justification, but you don't really provide it. If the best BLR has are their players in CHL, then it is a resounding no even with 2003 and 2004. 2002 Is obviously not comparable
