This one is a no brainer.
NBA Hall of Famer and ten-time All Star Clyde "The Glide" Drexler is the best scorer ever to play for Portland.
"The Glide" played for Portland from 1983-1995.
He averaged 20.4 points per game during his 15-year NBA career. His best single season was the 1988-1989 season with Portland when he posted a 27.7 points per game average.
Drexler scored 18,040 points while with the Blazers, which is almost 7,000 points more than the next closest, Terry Porter.
Clyde Drexler's versatility as a player and amazing athletic ability helped him to have an extraordinary NBA career as well as playing on the "Dream Team" and many All-Star games.
Clyde would definitely garner plenty of talk in a debate on the greatest Blazer ever, but on this list he's No. 1 as the best scorer to play for the Portland Trail Blazers.
