Meh, I'm not a fan of these "what would the table look like without player X" statistics as they lead to the assumption that a team plays without one player, in other words.. with only 10 men. Like you said, Ronaldo's 4 goals against Elche helped Real to win, but if Ronaldo wasn't there, maybe his replacement would've scored (at least) one goal, which would have been enough to win against Elche, too.
‘" went through every La Liga result and subtracted the goals scored by Messi and Ronaldo, altering the resulting final score. So, for example, if it weren’t for the 4 goals Ronaldo scored against Elche in 5th round, the game would’ve ended 1-1. This way, Real would lose 2 points and Elche would gain 1.
‘Obviously, I’m not trying to prove who the best player is or anything like that. Basically, I did this avoid other, more important things that I should be doing."
