Writing for FiveThirtyEight, certified athletic trainer Jeff Stotts endeavored to envision an alternate reality in which no NBA players suffered any injuries in the 2013/14 season. With an assist from Advanced Statistical Plus/Minus, he simulated an injury-free season and compared those results to what took place here in reality.
Broadly, Stotts finds that the season would have gone just about the same: the Phoenix Suns would have edged the Memphis Grizzlies out of the Western Conference's final playoff seed, but otherwise the bracket would have remained intact.
As for how this injury-free utopia might have affected the Orlando Magic, the answer is a resounding "not much." In Stotts' simulation, the Magic finish with a .268 winning percentage, which figure translates to one fewer win than the 23 victories they posted in real life. "The Magic aren't notable in either reality," he says.
In 2013/14, Orlando mostly remained healthy, with two notable exceptions: starting center Nik Vučević missed 25 games with a variety of ailments, including a concussion and a sore left Achilles'. Backup forward Tobias Harris missed 21 of the team's first 22 games due to a sprained ankle he sustained in the preseason, but played every game thereafter.
Still, the Magic's overall talent level is such that having everyone available for all 82 games--in which case everyone would have received a Golden Hammer--wouldn't affect their record much in either direction. The rest of the league is too strong when fully healthy.
