Scott from San Diego asked during the most recent chat what would stop the San Francisco 49ers or any team home for the playoffs from watering or drying out the playing surface to suit their style of play.
I didn't get to this question during the chat because I didn't have an air-tight answer. But according to NFL officials, the league sends a representative from its football operations department to each stadium. The official visits the stadium the day before the game to review field-maintenance plans with the team.
We should not expect to see the rogue sprinkler operator from those restaurant commercials, in other words.
