6. LaMarcus Aldridge
Despite leaving Portland and signing with San Antonio as a free agent in 2015 just as Lillard and CJ McCollum were becoming one of the best backcourts in the league, LaMarcus Aldridge is a Blazers fan-favorite and one of its best all-time players.
He was a 2006-07 First-Team All-Rookie selection, and after becoming a full-time starter the next year, LA averaged 20.5 points, 8.8 rebounds, 2.1 assists and 1.0 blocks across the next eight seasons. He made four consecutive all-star teams with the Blazers, three all-NBA teams and finished in the top-10 in MVP voting in '13-14 and '14-15.
Even if it didn't lead to any deep playoff runs in Portland, Aldridge's PER of 20.3 is one of the best in franchise history.
