I wrote an article a while back found here about Artis Gilmore and why he hasn't been enshrined in the Hall of Fame. He was a tremendous force both in the NBA and ABA.
To me, there is no question that he is one of the most underrated big men in basketball history.
His numbers speak for themselves. For his career combined with the NBA and ABA he averaged 18.8 points, 12.3 rebounds, 2.3 assists, 2.4 blocks, on 58.2 percent shooting, and 71.3 percent from the free throw line.
Gilmore played five years in the ABA before joining the NBA. His best season in the ABA was 1971-1972 when he averaged 23.8 points, 17.8 rebounds, 2.7 assists, 5 blocks, on 59.8 percent shooting, and 64.6 percent from the free throw line.
For his best season in the NBA it was in 1977-1978 when he averaged 22.9 points, 13.1 rebounds, 3.2 assists, 2.2 blocks, on 55.9 percent shooting, and 70.4 percent from the free throw line.
When combining the total numbers he had 24,941 points, 16,330 rebounds, 3050 assists, and 3178 blocks.
He was a five time ABA All-Star, six time NBA All-Star, ABA Rookie of the Year, ABA MVP, ABA Playoff MVP, five time ABA First-Team Selection, four time ABA All-Defense First Team selection, and a one time NBA Second Team All-Defense selection.
Was part of one ABA Championship team.
Gilmore combined ranks first in field goal percentage, fourth in blocks, fifth in total rebounds, eighth in minutes played, eighth in free throw attempts, 10th in games played, 16th in free throws, 19th in field goals, and 20th in points.
