Injuries have often adversely affected teams with a realistic chance of winning an NBA championship. Most notably in recent history, between 2009 and 2012 the Boston Celtics suffered injuries to key players that greatly decreased their probability of winning championships. Likewise the Chicago Bulls lost Derrick Rose to injury in Game one of their 2012 Eastern Conference Quarter-final series against the Philadelphia 76ers which essentially killed any chance they had of winning a title last season.
This trend has continued in the 2013 postseason, with the Golden State Warriors losing All-Star forward David Lee and the Oklahoma City Thunder losing All-Star point guard Russell Westbrook for the duration of the year. Granted, even with Lee the Warriors were not considered a serious contender to win this year’s championship. But, should they be able to defeat the Denver Nuggets in the first round, losing Lee will make it extremely difficult for them to defeat the Spurs in the second round or any opponent in the Conference or NBA Finals.
