The NBA is back in full swing, already a game or two under each team's belt. So I'm late with my prediction, but here it goes anyway.
Boston will still be the "team to beat", but I think another year older is going to play out to their disadvantage. Come the end of the season when it REALLY matters, the younger Lakers will meet them again, and this time prevail.
Watch out for the Trail Blazer and Heat too, they could rise up and slay one of the titans in the East/West this year and make it to the conference finals.
But I'm going with Phil Jackson and the Lakers as my 2009 NBA champion.
