Being a former Phoenix resident (and currently living in an east-coast city with no NBA team), I follow the west more than the east. Here are my thoughts:
1) Lakers: The path to the championship still goes through LA. If Bynum is playing, then these guys are favored to win the west. But, there are some vulnerabilities. For one, their bench isn't as good as the past couple of years. You got Odom coming off the bench, but after that, no one that's really great. That means the starters are playing more minutes and Kobe has to be more involved. Why is that a problem? Point 2, Kobe can be a ball-hog. And if he's not on, he wants the ball even more. It can be a slippery slope. Lately it seems like he hasn't been on as much as in the past, so this could be an issue. Is it enough to beat them four times? I don't know. Stranger things have happened before, but their match-ups (OKC, and Denver/Utah) don't fill me with a lot of confidence. My prediction Lakers get to the western finals.
2) Mavs/Spurs: This one is a head-scratcher. Can the Mavs put away the Spurs? The Suns fan in me hopes so.
Normally, I'd call it in favor of Dallas, but they're playing the Spurs. Every year the Spurs death watch starts and continues until they either win it all or get to the finals. They have the talent on paper to get it done again.
The Spurs aren't your typical 7th seed. To paraphrase the words of the great Dennis Green, the Spurs are who we think they are. If the Spurs Big Three play up to their typical level in the playoffs, then the Mavs are done in the first round.
That being said (written?), the Mavs hard-charged their way to a 2 seed in one of more ridiculously competitive conferences in pro-sports. The Mavs are no shrinking violets. They have the talent to send the Spurs home. Jason Kidd is playing well, as is Nowitzki (sp), and they have that annoying fucker Jason Terry who plays fairly good defense and who can shoot pretty well too.
So who wins? Since I bleed Purple and Orange, I hope it's the Mavs since I don't want to see San Antonio at all until the next year. Talent wise, I'd say it's a push or slightly in favor of SA. So, I'd say Spurs in 7, with Popovich's skills as a coach giving SA the edge.
3) The Phoenix Suns
I think they'll get by Portland in 5. Portland's too banged up and the Suns are on a tear. After that -- who knows? I like them better against the Mavs than I do against the Spurs. If Robin Lopez is back in the line-up, then I think they got a good chance at getting to the western conference finals, regardless who they play. But I still don't think they can get through LA to hit the finals. I'd love to be wrong, but I don't know that they can handle Phil Jackson and his two seven footers, to say nothing of Kobe.
4) Utah/Denver
Denver in 6. Don't ask me why. Intuition.
