Nice strawman.
I never played the game at anything beyond high school. However, I when I did play, I played defense. I know full well that most people ignore defense until someone screws up. You sound like one of those people.
Please look any Barcelona game and see what Iniesta does at the moment team loses the ball. Defending does not equal tracking back, tackling and hoofing out of the box.
Zidane was overrated, I don't think Iniesta is anwhere near Xavi, but he's better than Zidane
It's harsh to say overrated, but being an esthetically pleasing player and matchwinner he was a media and fan favourite and some of his shortcomings were overlooked. Exactly opposite compared to the case of Iniesta.
I would put Xavi out of all categories, as a player that epitomises football intelligence. He was always such a classy, composed and supremely intelligent player,from his first days, but I always thought that his lack of strength and pace will be exposed in modern football. Fortunately, FC Barcelona redefined the game and Xavi IMO is an all-time archetype of The Playmaker.
However, I believe it's completely wrong to say Iniesta is "nowhere near" Xavi. They're different. Obviously Xavi is superior as a playmaker. But then, Iniesta has other qualities that make him the best midfielder I've ever seen, even if this sounds little over the top. But the thing is, I've never seen a midfielder this mobile, active and overall brilliant.
