Two different questions
Asking whether a league is strong and asking whether it is interesting are separate questions, and Dutch football is a clear case of the answers diverging. Continental results are shaped mostly by wage bills, and Dutch clubs are not competing at the top of that market. What they do offer is teams that attempt things, coached by people who can explain their reasoning, playing squads young enough to make mistakes worth watching.
If your only interest is who lifts trophies in May, that is a coherent position and this is not your league. If you enjoy watching a coach solve a problem, it is one of the best.
Youth makes it volatile
Because these squads are young by necessity, matches swing. A side that controls forty minutes can lose its structure entirely after conceding, and a nineteen-year-old who was invisible in one half can decide the game in the next. Purists sometimes call this a lack of control. I would call it the reason the fixtures are worth ninety minutes of attention.
The trade-off is honest and clearly signposted: fewer polished performances, more matches where you genuinely do not know what the next twenty minutes will look like.
