Portland Trail Blazers owner Paul Allen and general manager Neil Olshey formally presented the representatives of three-time All-Star forward LaMarcus Aldridge a maximum contract extension in Los Angeles last week, league sources told Yahoo Sports.

Allen and Olshey met with Wasserman Media Group agents Thad Foucher and Arn Tellem to lay out the max contract extension scenarios available to Aldridge and reaffirm the franchise's desire to secure him for the long term, league sources said.

With only a remote chance that Aldridge will agree to the three-year, $55.5 million extension afforded him this summer under the collective bargaining agreement, the Blazers are determined to keep Aldridge on a five-year, $108 million extension that he can sign upon reaching free agency next summer.

Aldridge has publicly and privately expressed a strong desire to stay with the Blazers, and there's believed to be significant momentum toward him ultimately recommitting to Portland. The fact that the owner and GM made the trip to present the offer face-to-face wasn't lost on Aldridge's camp, sources said.

In a career-best season, Aldridge averaged 23.2 points and 11.1 rebounds in leading the Blazers to the Western Conference semifinals. Aldridge was selected as a third-team All-NBA player.
