LeBron James and the Los Angeles Lakers now have a commanding 3-1 lead over the Miami Heat in the NBA Finals. Despite this, James is not resting on his laurels.

Despite their great Game 4 victory, James isn't looking too far ahead. He knows that a lot still has to be done before they could win the title.

Besides, the bubble games have played out very differently from games in NBA arenas. One telling difference is the fact that two teams have blown a 3-1 lead in the bubble. Both the Utah Jazz and the Los Angeles Clippers had a commanding 3-1 lead over the Denver Nuggets and simply blew it.

Apart from this, many upsets have occurred in the bubble as well. In the second round of the playoffs, the Heat booted out the Milwaukee Bucks in five games. Note that the Bucks were the best regular-season team and were poised to win the title this year.

Besides, LeBron James has been down 3-1 in an NBA Finals series. He knows that it's very possible for any team to come back from that deficit and snatch the title.

Well aware of these facts, James and the Lakers have embraced the “job is not done” philosophy throughout the playoffs. When they won the Western Conference title, they celebrate for a minute but went right back to business. When they were up 2-0 against the Heat, every single Laker was not satisfied nor happy.

Game 5 of the NBA Finals will be on Friday. Will the Lakers claim their 17th title in franchise history? Or will the Heat remain alive?
