The Era of PG Dominance?

It's hard to say that it is the era of PG dominance in the NBA as probably the top four or five players in the league all play different positions, ie. Kobe, LeBron, Wade, Durant, Howard and also the Lakers just won the title last year without a dominant PG. And I would say that the front runners for the title this year are lacking the dominant PG, Lakers with Fisher, Cavs with Mo Williams(good but not dominant), and Magic with Nelson(again good but not dominant). The PG is an improving position and I do think that most of these players will be great for a long time but remember when was the last time that a team who's best player was a PG won the title? Maybe Detroit with Billups otherwise you would have to go all the way back to Magic's Lakers...and Magic was a once in a lifetime kind of player as a PG.
