NBL EXPERIENCE

Martin Barmentloo made his NBL debut with the Geelong Supercats on 17/4/1993. He scored two points in his first game.

After the team was gutted in 1992, a move which resulted in Geelong finishing with just two wins for the season, the Supercats were able to regroup and add to their wafer-thin roster of last season. Vince Hinchen (via Melbourne) would return after a season playing with the Tigers, and Ray Borner (via North Melbourne) was signed to help fill a gaping hole inside. Imports Bobby Locke and Chris Williams were replaced by Adrian Branch, who had won a NBA championship with the Lakers in 1987, and Mike Morrison, who had just finished up a stint with the NBA’s Phoenix Suns.

Six games into the season, the Supercats received a letter from coach Steve Breheny, which outlined he felt he did not have the support of the club. It was reported that he did not want Branch as part of the team, but the club chose to sign him to a two-year deal anyways. After a loss to Melbourne, Breheny brought Branch off the bench in their next game against Adelaide, feeling he cared more about stats than winning (a sentiment echoed by his former Brisbane coach Brian Kerle). Geelong would win this game (113-100), with Branch playing 36 minutes and scoring 30 points. Branch then skipped trainings, prompting Breheny to pen a letter to management asking for their support or agreeing to re-sign. The Supercats (2-4) accepted his resignation and continued the season under interim coach Terry Kealey. Jim Calvin was hired as a permanent solution shortly after.

Branch (26.9 points, 8.4 rebounds, and 1.9 steals) would go on to lead the team statistically, with Morrison (22.3 points, 3.8 rebounds, 4.1 assists, and 2.2 steals), Cecil Exum (16.6 points, 9.5 rebounds, 2.5 assists, and 1.4 steals), Borner (16.4 points, 10.2 rebounds, and 1.3 blocks) and Vince Hinchen (14.3 points, 2.9 rebounds, 2.1 assists, and 1.1 steals) adding support. The team saw very little support from the bench, with its starting five all playing a minimum of 35 minutes a game and only Wayne Larkins (6.3 points, 2.6 rebounds, 4.2 assists, and 2.2 steals) playing meaningful minutes off the bench. The team basically played with six players for the entire season.

With three rounds left, Geelong sat equal last alongside Hobart and Townsville, all three team’s sitting on four wins. Geelong, however, reeled off three wins in a row to end the season, knocking off Sydney (126–115), Gold Coast (113–108) and fourth-placed Brisbane (118–115) to end the season on a high note.

Barmentloo appeared in 18 games, averaging averaged 2.0 points, 1.1 rebounds, and 0.2 assists as the Supercats finished with a record of 7-19.
