Cal State East Bay head basketball coach Bryan Rooney discussing his team's historic 33-1 season and their connecting style of play. Rooney explained how his team implemented the "tagging up" system where all five players engage in defensive rebounding immediately after shots go up, creating pressure defense and transition opportunities. He detailed how the system connects full-court and half-court defense, emphasizing that defensive engagement starts as soon as possessions are decided rather than waiting for specific situations.

Bryan Rooney has won over 300 games and during the 2025-26 at East Bay, Rooney guided the team to a historic 33-1 record, a perfect 22-0 CCAA mark (first undefeated conference season in league history), CCAA and NCAA West Regional championships, and an Elite Eight appearance. For this performance he was named the 2026 Clarence “Big House” Gaines National Coach of the Year, NABC Division II National Coach of the Year, and CCAA Coach of the Year.

Rooney discussed the importance of playing "complementary basketball" where offensive and defensive efforts support each other, and shared how they tracked metrics like corner touches and transition grading to monitor player development. He also explained how his coaching staff operated with defined roles, allowing Rooney to focus more on leadership rather than specific tactical decisions. The coach emphasized the program's focus on "transformative" player development and role clarity, noting that players were encouraged to understand their interconnected responsibilities rather than individual statistics.
