This is a necessity for a number of reasons. Number one is that the players want it. For the 08' season every SBC team except FIU & FAU will have turf installed. It will also help with consistency of play. I've read a lot of info on the Turf and no one has correlated a higher injury rate with the Turf.
Same goes for baseball. Consistent play and a lot of the players who have played on the surface really like it. Tulane has it installed and Lamar is currently installing it.
I know it isn't traditional but when add up the fact that the players want it, reduced maintenance cost, consistent play, and reducing rainouts it is hard to argue against it.
