It’s not often Texas A&M fans in Georgia have the chance to pose for photos with Reveille, the collie mascot. It’s a similar rarity to see Missouri mascot Truman the Tiger high-stepping through the halls of an Atlanta hotel. LSU? Auburn? No, this is a different cat. Reveille and Truman have a new conference home, and introductions were in order on Wednesday night. Southeastern Conference commissioner Mike Slive and the SEC held an official welcoming party for Missouri and Texas A&M, only three months before the Tigers and Aggies open their first football schedules as members of the conference.
