I've never understood the appeal of playing on FieldTurf of any other synthetic turf, but all of the football players at my school down here in Texas desperately want our grass field replaced with the stuff. I spoke to my AD a couple weeks ago and he's pretty sure that by 2020 we will in all likelihood do it, as they've already gotten estimates (apparently about $1.3 million). But yeah, as bees said the new, more revolutionary stuff, doesn't have many pellets...it's an actual, long-ish, synthetic grass that's got some silica fillings to sustain it and keep it from getting beaten and worn down.
