If the Blazers had another yr of playoffs experience under their belt, I would pick them to win the west as of today with the rosters of the other teams considered.
The lakers got Artest, but he won't be content to take less than 10 shots per game per 37 mins of playing time like Ariza. There is only a certain # of shots to go around per game. Artest's shots will come at the expense of others. I would prefer Pau taking more shots than giving them to Ron.
The spurs are better with Jefferson but still need another big to contend. If they get Rasheed, they are up there with the lakers.
But no one has the talent of the Blazers at this point. If Greg Oden develops more for next yr and can stay out of foul trouble, he will be a force with rebounds and protecting the lane. Oden, Aldridge, Hedo, Roy, Blake.... thats a good starting line up. You still have guys like Rudy, Batum, Outlaw, Pyzibilla coming off the bench.
