More competetive doesn't equal stronger.
If all the teams achieve a higher consistent quality over a season the league gets stronger even if that includes the best team running away points wise. If all the teams dip in quality on a consistent basis throughout a season the league gets weaker, and a normal effect of that is that points tallies evens out. Then you have to see if it evens out because there is more quality in the league so everyone can take points from anyone, or if performance levels are poorer/more inconsistent. In my opinion it is clear that this is a year of poor quality/consistensy across the board, from 1st to 20th. The point tally, and what differs 1st from 10th or 12th to 20th is irrelevant for the quality of the league.
3 teams fighting for the league is certainly competetive but if 2 of them are the same teams that have usually fought for the title over a number of years but they are both much worse, while the third team is in and around their current level, how can that equal stronger league?
More exciting maybe
