I like to think I paid attention in English class, but this is the first I have heard of conjugating collective nouns in the plural. We would never say, "the team are good," "these deck are stacked," or "some paah are dangerous." We often refer to team members/executives in the plural (e.g. "Green Bay will fail unless they add more defensive talent") but never the team itself (e.g. "San Francisco only won four Super Bowls because their pitifully weak division guaranteed them playoff berths.")
