Whether the injury itself is freaky or not is irrelevant.
Kyrie Irving is prone to injury and he's playing for USA basketball in a time when LeBron is returning and Kevin Love is on the clock to join Cleveland for a title run. A title that Cleveland hasn't experienced in 50 years. USA basketball will dominate with or without Kyrie. It's not worth it.
The experience to play alongside Kevin and LeBron James is once (possibly more) in a lifetime. If he's going to injure himself, he had better damn well do it while playing his heart out for the Cleveland Cavaliers.
We don't read all the articles of every Joe Schmo in AAU who suffered horrific injuries. The fact is most horrific injures occur without bone fractures or gruesome pictures to show for it.
Let's not test injury fate because it happens close to every single night during the regular season of the NBA. The more time you spend on the floor as a professional, the more likely you are to suffer an injury.
