LeBron James signing with the Los Angeles Lakers means a couple different things for the Boston Celtics.
For starters it means that the Celtics are now the overwhelming favorites in the Eastern Conference. Boston was one game away from the NBA Finals without their two best players and if they return healthy, the rest of the east stands little to no chance of stopping them.
They have one of the best coaches in the NBA, one of the best starting lineups and the depth to compete with anybody.
