You've got a hard on for Xavi - who exploded into the scene at the age of 27-28 with the emergence of Messi, Iniesta and Busquets. Before that, his output was nothing to write home about. He wasn't particularly strong, fast, skillful in dribbling or getting into the box - he was a great system player that was born in a rondo with Iniesta/Busi/Messi/Alonso etc. Not taking anything from his brilliance, but he shone brightest in a particular system.
Feel Modric has more to his game on a technical level and versatility - not to mention longevity
To make your point, you've done exactly what I was referring to. Xavi is no more at 'fault' for his supporting cast than practically any other all-time great not named Maradona. Or should we reduce others in these tiers because their team-mates rendered their contribution a redundancy out the box?
The last team-mate Xavi had who had more influence on midfield than him was Marcus Senna, but during Xavi's rise and period of dominance, there isn't a name that goes before him as the midfield metronome - he is the top 1 of 1. Unparalleled at what he did. In any fantasy lineup for a retentive midfield, he's the first name that goes into that role as the influence and control exerted is nothing we've seen before or since. If you'd like to put a name forth over Xavi for this, go ahead; I'd like to see what you'd come up with, truth be told.
I don't know whether it's a 'hard on' for Xavi, or just plain acknowledgement of what he was and what place that earns him in the history of the game. I feel as though his is a name people want to dilute or reduce for reasons that cannot detract from what he did for his club and country. You mention him being part of a particular system - the reality was, he
became the system i.e. 'we pass to Xavi, wait for his lead and become satellites orbiting him all game' exactly how the DLP version of Scholes dictated everything for us, on a grander scale with even more control and influence.
re. the age of his ascendency and rise to absolute prominence. I'm not sure that's so important in a discussion like this. That's reserved for the chosen ones who were earmarked to become the greatest players of all-time in their teenage years. The likes of Maradona, Pele, L.Ronaldo, Messi and so on and so forth. Absolutely nobody had Xavi or Modric penned as what they became in their early 20's - you can't beat one with that brush when the case is the same for the other (who was literally a figure of ridicule on this very site during his time at Spurs, with the majority believing him not to be good enough to come to us! The prophet, Scholesly, stood alone in his foreseeing of what Modric became). They weren't prodigies in the same sense as the aforementioned, but nor do they need to be to take part in such a discussion.
And yes, you are clearly taking away from his brilliance; I don't think you've particularly highlighted his brilliance in the entirety of your post, rather, you've stated the things you perceived him to
not be good at, then reduced him to a system player.
re. Modric having more to his game, that would depend on the context of discussion. The general consensus regarding Xavi's game and tools he utilised to make his game possible is that he's the best at those things with a level of nuance that is barely acknowledged by the wider audience at large. His shape to receive the ball; to turn out or in with it; his manipulation of the ball and resets to receive it again and again and again; his processing of angles and timing of those actions - it doesn't matter who you put there to rival him, as a package, there's a reason why he holds the esteem he does as the consummate or apex player of his type.
I don't know whether that should exist in a bubble, but it certainly shouldn't be swept under the rug or played down - it's gotten to the point where the people that would speak up about it don't really do so anymore because it's a thankless task for them. I only mention it now myself, because I see the same patterns repeating on themselves as have been for at least the last 5-years, and it's really a curious affair to see a player of such influence and impact on the sport - itself - slowly but surely be scrubbed from the consciousness as Xavi is being. Maybe the other pinnacle player in a position this happened to is Gerd Muller, but even he has had a renaissance in the public consciousness compared to in the past where his goal-scoring skills were looked down upon in numerous ways.
