Starter: LaMarcus Aldridge
Backup: Channing Frye
Backup: Ike Diogu
Much like the center position, the key at power forward for the Blazers is depth. 
Both Aldridge and Frye would probably start on most NBA teams. Heck, Diogu might even start or see actual minutes on a few NBA teams. Aldridge will be the starter all season, there is no a threat from Frye to take that role. As Aldridge continues to develop, I see him playing 35 minutes a game. That might sound like a long time, but he’ll prove that he has the stamina and ability to justify that amount of playing time. I see him being a guy who can get 20 points a night with some consistency. The center position (Oden or Przybilla) will do the bulk of the rebounding, which works well with Aldridge since that is his weak spot. He will really become the offensive threat in the “Twin Towers.”
The depth for the Blazers in the power forward position comes down to how far Frye has developed this summer. He has been working out in Portland with Oden, as seen in some of the released videos. He hasn’t spent all summer in Portland, there are sightings of him and Bayless down in Tucson, AZ.
I see Aldridge getting a lot of focus once Oden goes out of the game. And I do see plenty of times when Aldridge is in the game without Oden. Like I mentioned in the “centers” post, I don’t see Oden playing over 20 minutes a game, especially at the start of the season. He will be slowly introduced to the offense and see more minutes, but Aldridge will be a go to guy on night one. Frye can also step up on day one. 
My issue with Frye is consistency. I know he is capable of going for 20 a night, but those nights are rare and extremely inconsistent. I think he will be used much like he was last season, if he comes out shooting (which he will) and is off, Nate will pull him and he will all but be done for the game.
So who goes in for Frye? Our new addition, Ike Diogu. I haven’t seen Diogu play much in the NBA, because well…he hasn’t played much in the NBA. But I do remember him tearing it up in college. He was a huge star at Arizona State University. He’s small, at only 6′8″ for a power forward, but he is a solid 250lbs. He averaged about 6 points (5.6) in 10 minutes per game last season with the Indiana Pacers. That’s not terrible production, and with a solid “true” center in Przybilla (since Przybilla will probably be in the game when Diogu sees the majority of his minutes), Diogu will be able to play more of a floating power forward role. The pressure won’t be on him to crash the boards, that will go on Przybilla. I don’t see Diogu playing that influential of a role for the season, but I can see him being the difference in 2-3 games. That alone is worth it to bring him in and give him a chance.
LaMarcus Aldridge is going to emerge this year as a premium power forward in the NBA. He and Oden will begin to show what a dominant force they will be in the future. I don’t know if there is any team that can match up with Portland for 48 minutes at either the power forward or center position, let alone both.
