The reluctance to concede that Messi's season was not as disastrous as first thought is amusing. If it was any other player , a figure of 25 goal involvements would be lapped up immediately. But because it's messi, people will claim that assists are not a big deal and at the same time go look up some subjective xAssists stat to 'prove' that the assists where not great enough!
While I too see his season as an overall failure, it was not anywhere as bad as people are making it out to be - that's a fact that is derivable from his individual stats for the season.
Of course stats don't tell the whole story but here it is useful. It's not only assists - he has good numbers in other metrics as well, like key passes, dribbles etc. He has comparable numbers to the top players in different metrics and people claiming he has lost it are clueless imo. Natural decline aside, I think his game is still very good.
