He was a sophomore on a team that had two future NBA players on it. Elder, La Salle, and St. X are three opponents and even if they play each of them twice it accounts for just about a quarter of their schedule. And St. Xavier has a good basketball program.
For some perspective, during Duncomb's senior year his team lost 58-57 in OT to Lawrence North who was the Indiana State runner up in 4A, they beat Akron St. Vincent-St. Mary with Malaki Branham and Sencire Harris (LeBron's high school), and beat Centerville (Cupps team as a sophomore) in the regular season by 13 points but later lost to them in the regional final. Centerville went on to win the state finals that year and won 30+ consecutive games and was a top 10 team in the country at one point. Moeller was the last team to beat Centerville until they lost in last years state finals.
