Both his brothers were good players. As a junior at Seton Hall this year PG Sterling Gibbs averaged 16.3 ppg and 3.8 assists, and was named second team All-Big East. He was their best player.
Older brother Ashton Gibbs was a 3 year starting PG for Pittsburgh (backup as a freshman) and averaged about 15 ppg his last 3 years. He's still playing internationally. As a sophomore he was 2nd team All Big-East and was voted the most improved player in the conference. He was 1st team as a junior when Pitt won the conference and only honorable mention as a senior. Some stats that jumped out at me shows he can shoot. As a junior he averaged 89% from the FT line and 49% from the 3-point line making 102 of his 208 attempts.
TJ obviously comes from a good pedigree of basketball family.
