Why was so much expected of the Lakers this season

I understand that the Lakers acquired LeBron James in the off season, but expecting him to turn a team that only won 30 games around into a championship contender in one year seems a little ridiculous in hindsight. Is he the only reason why expectations were so high for LA this year? Or were other factors contributing?
