Cleveland's elimination was very anticlimactic--they were pegged midseason onwards to pretty much be in the Finals. Now that's no longer possible...
I think the Magic built some momentum and confidence beating the Cavs and Celtics--these were the two best East teams last year, and arguably two of the best this year. Their strategy of surrounding a dominating big with three point shooters is a real recipe for success--as Cleveland found it, it's just hard to guard everyone at once.
The Lakers stumbled their way through the last two series, but they gained some momentum with their last several games against Denver, and judging from their WCF trophy presentation they seemed like they were all on a mission. They're a very deep team on paper that doesn't always play up to its full potential due to bouts of laziness and going through the motions, but if they put their minds up to it (theoretically they should, since it's the biggest stage and many of them went through the embarassment of Celtics defeat last year) they should take this series from the Magic.
Granted, a lot of variables are in play--many matchups to look at, such as how Andrew Bynum and Pau Gasol (the supposed "twin" towers) handle Dwight, although Bynum's been way off so it's a real enigma for the Lakers here. The Lakers couldn't handle Dwight early in the season, so I'd say the Magic got the better end of this one. Then there's the one with Mickael Pietrus and Courtney Lee--I thought they did as good a job as they could on Bron (of course LeBron still got his numbers), but I'd like to see how they handle Kobe. Then the Magic three point bombing and Dwight dunking--if things are clicking on all cylinders as the have with the Cavs, then it can be a real irritant on the Lakers, especially since the Lakers are prone to having defensive lapses.
But I do think the Lakers match up better than the Cavs--Ariza and Odom have the length and athleticism to crossmatch with Turkoglu and Lewis, and while Dwight should have his way with the Lakers, the Lakers still have height and length galore, so I don't think it's as easy a matchup as it was with Cleveland. And Rafer Alston and Derek Fisher sort of neutralize each other--I've never been a fan of Alston's decision making and unreliable jumper, and Fisher's having a bad playoffs. If Jameer Nelson were still playing he might turn the tide--he torched the Lakers, and Alston can't expose the Lakers' guard weakness. And Kobe should have good games where he wills the Lakers to victories.
So end of the day, I think the Magic will win several games by virtue of their threes and Dwight dominance, but the Lakers might have the greater motivation, willpower and talent level, while having fewer matchup problems than the Cavs. So I'd say the Lakers in 6 or 7. I like the Magic, but they seemed to come from lukewarm good team to suddenly respected when we're talking from the start of the season to now, and I just don't think they have quite the experience yet to pull this off...
