The reason why you see a higher number of schools with turf or indoor facilities go deeper in the playoffs have more to do with the fact that athletics is important at that school and is invested in. Usually these schools pay better which gets better coaches. Better coaches get more investment from the players which leads to better results on the field. Now Indoor facilities probably have more to do with success than turf does due to the fact that you will never miss a practice due to bad weather and you wont lose your legs in August and September. Turf over time does pay for itself. There is that argument also which is legitimate. SETX is behind the times when it comes to facilities in general. Heck take a drive up to mid to north east texas and you will see a bunch of small schools with turf. Go to Texasbob.com if you dont believe me.
