I played on astroturf in the 80's...we called it fuzzy cement, and that was not the worst adjective I ever heard it called. While I never dressed for a game at BDS or Legion Field, I practiced on the same kind of turf every day, unless we moved to the grass field for practices, which, back we didn't do a whole lot. In 2011 I played in a charity game (full pads/contact) on a field with artificial turf similar to what Ole Miss uses. I hated it. You either cut and lost your footing or you cut and your cleats held on too firmly, which is a recipe for disaster for knees. I would never, ever, ever, ever be in favor of changing from the natural turf at BDS.
