Xavier's starters are in their fourth, fourth, fourth, third, and third years as college basketball players. They are all old enough to buy alcohol, as is the first guy off the bench, who is in his fifth year as a collegiate competitor. The rest of the rotation is made up of freshmen and Dontarius James, but Xavier is still the 65th most experienced team in the nation (per KenPom). The only teams in the league with more experience are Providence, Butler, and Marquette; those three are a combined 6-2 in the Big East.
Xavier, you may be aware, is 1-2.
