The use was not widespread in 2002. It was only in a handful of college stadiums and had only been put in one NFL stadium.
Also it's changed a bit since then.
I've played on everything including the original astroturf. (Astroturf was literally on concrete or asphalt with a carpet pad over the top.) I've also coached and officiated for years on field turf. You notice a huge difference on your joints, especially knees and feet, after you've officiated four football games in a row on field turf vs grass.
