1. Damian Lillard
Damian Lillard is the most beloved player in Blazers history. And while it may not put the conversation entirely to bed, his 22.5 PER helps his case to be the greatest.
Dame is No. 1 in franchise history in threes, free-throws, free-throw percentage, offensive win shares, offensive box plus/minus, points per game and total scoring. He started from day one of his rookie season and averaged 19.0 points on his way to winning Rookie of the Year. He averaged 25.2 points, 4.2 rebounds, 6.7 assists and 1.0 steals with shooting splits of 44/37/90 during his Portland career.
Lillard made seven all-star teams with the Blazers, seven all-NBA teams, and earned MVP votes five times. He won the 2018-19 J. Walter Kennedy Citizenship Award for his work in the Portland community.
Drexler and Walton are in the conversation to be the greatest player in Trail Blazers' history, but Lillard wins the PER piece of the argument.
