(Portland, OR) -- It's been a long time since he left Portland, but LaMarcus Aldridge will always be a Blazer for life. Aldridge announced Thursday he is retiring after 15 seasons due to issues with an irregular heartbeat. The number-two pick of the 2006 Draft, Aldridge was a seven-time NBA All-Star, four times as a Trail Blazer. He is also Portland's all-time leading rebounder.
