He signed to play for the West Adelaide Bearcats in the 1982 NBL season joining such players as captain-coach and the league's first ever Most Valuable Player Ken Richardson, Australian Boomers veterans Peter Ali and Ray Wood, and South Bronx-born guard and 1982 NBL MVP Al Green.
Following the 1983 season when West Adelaide lost the Grand Final to the Canberra Cannons, Loggins returned to the Brisbane Bullets where he would play for the remainder of his career.
Game 1 of the series was at the Entertainment Centre where a then Australian indoor attendance record crowd of over 11,000 was set, including celebrities such as international cricketers Greg Chappell and Ian Botham.
The 36ers steadied though and helped by both Loggins (who scored 38 points) and Larry Sengstock fouling out in the 4th quarter, ran out winners in overtime.
Brisbane finished the regular season in second place behind Adelaide and made it to their fourth grand final in a row, this time playing the Perth Wildcats who had upset the defending champion 36ers in their three-game Semi-final series.
Loggins MVP form continued in the grand final series as the Bullets swept the Wildcats 2–0, averaging 26.5 points over the two games.
Brisbane returned to form in 1990, fighting their way into the NBL Grand Final series against the Perth Wildcats, but couldn't overcome the talented Cats who included such players as James Crawford, Ricky Grace, Mike Ellis and former Harlem Globetrotter Kendal "Tiny" Pinder, as well as being coached by his former Bullets championship winning teammate Cal Bruton.
During his career, Loggins was also selected to numerous NBL All-Star Games, winning the first two-game MVP awards in 1982 at the Apollo Stadium in Adelaide and again in 1988 at The Glass House in Melbourne.
Loggins would eventually retire after 21 seasons in the NBL despite still being an integral part of the Bullets line-up at 43 years of age.
Leroy Loggins retired with a then record 567 games in the Australian NBL, although this has since been surpassed by both Andrew Gaze[3] and Tony Ronaldson.
