Personally I do not think artificial turf at Cajun Field is a good idea, or a wise use of money. In the early 90's the field looked GREAT for every game, and it could look that way again for a fraction of the cost of the turf. Mud is only an issue if it rains during or immediately prior to the game. After a few minutes the excellent drainage system does its job.
But, if the athletic department sees this as a priority, I have no problem with it.
However...one concern that I have is that Cajun Field is two feet below sea level, and relies on sumps and pumps to drain...those sumps are below the playing surface. Does artificial turf allow enough water to pass through its surface to keep up with a heavy rainfall? Remember on a normal field the water can drain off of the sides and everything is fine...not in Cajun Field.
