Kobe Bryant was pretty darn good last season, but this season he's leaner and meaner and should be fired up after a great performance in the FIBA Americas.  There is some worry about his discontent with the talent on the team, but that's been going on for years. Expect him to be stellar as usual. 
 

Likewise, Dwayne Wade's numbers were superb last season.  Of course, his high turnover rate is a lot to swallow.  On top of that, Wade has been extremely injury prone in his career and is scheduled to miss the first 2-3 weeks of the season.  Buyer beware with Wade.  He's a great commodity, but don't expect him to be around for a full season and be ready to take a hit in turnovers if your league factors them in the scoring system.
 

Here are the top five power forwards in fantasy basketball:

1. Kobe Bryant - Ranked #1 on Fantapedia's Player Rankings.  
2. Dwayne Wade - Turnovers and injury proneness keeping him out of the top ten. 
3. Vince Carter - Was playing for a new contract last season, but should continue to post great numbers.
4. Andre Iguodala - Versatile and only getting better.
5. Michael Redd - A great offensive weapon.
