I'm sure you don't need to be a genius to know tomdo was 'to do' and rola was 'role', but when writing in a smartphone sometimes you can accidentally push the letter next to the one you wanted and don't notice.
I'm sure that doesn't make my English worse, but you really need to take some syntax lessons.
Still that's not the point.
Saying that a offensive midfielder is amazing or better than an organizer because he can get 10 or more goals/assists combined in a season with 50 games on average is dumb and makes Iniesta look very average, when he is one of the best midfielders of his generation.
I agree that goals and assists are not particularly suited stats to rate someone like Iniesta or Modric. But Iniesta played a very similar role to him in Madrid. Yes, on average he probably played a little bit further up front but that has primarily to do with Barca's playing style and Iniesta and his abilities were an integral part of making this style possible in the first place. Additionally, most of these assists and goals are gathered in games against weaker teams and Madrid plays a very high line in these games, too, with lots and lots of possession.
Generally, it is just a case of a slightly different interpretation of basically the same roles because after all, Iniesta and Modric are pretty similar. But again, you are right when saying goals and assists are bad metrics to analyze the two. In some of Iniesta's best seasons he hadn't had much scorers while the opposite is true for some of his worse ones. Both players have different tasks to do which primarily consist of making midfield plays to set up their attackers, may it be through dribblings, one twos or key passes. Both are extremely good in it but for me, Iniesta just edges it. They are both extremely pressing resistant but Iniesta is better at "classic dribblings" in the sense of covering ground and beating one, two or even three defenders on his way towards the penalty area, if you ask me.
