Maintaining an impeccable multi-use grass field in Indiana isn't easy. (Just ask Purdue.) And Notre Dame has decided that it's become more trouble than it's worth for the Fighting Irish. Athletic director Jack Swarbrick announced during the Irish's Saturday spring game that Notre Dame Stadium's grass surface would be replaced by FieldTurf. The conversion will begin following the school's upcoming commencement, and be completed in time for the 2014 football season. "We had a strong predisposition to stay with a natural grass field," Swarbrick said in the announcement. "However, the reality is that in two of the last three seasons since we moved Commencement to the Stadium we have been unable to produce an acceptable playing surface. "That, combined with the likely impacts of future construction at the Stadium, led me to conclude that we would continue to struggle to maintain a grass field that meets the expectations of our student-athletes and fans as it relates to appearance, performance and safety." The "future construction" refers to an approved a $400 million stadium expansion project that will add three attached buildings to the venue and increase premium seating, among other benefits.
