Besides, his rating can not be a sound indicator for his performance. Truth is that he doesn't have access to talented and able-bodied players as other nations do.
After all, there're 7 teams left from LUX. Not everyone trains an NT-Lux prospect, or trains their players for the good of the country. 7 teams have access to a draft, where me and 2 other teams are consistently in the middle ground of the D.1 league, so we dont have pick priority as often as we would like to.
There are many other factors playing into this, but my point is that here's no point in discussing the qualities of a trainer without even considering other factors. Else we end up with loaded questions that are pointless for any party involved in a discussion.
