LeBron James posted an emotional tribute to Kobe Bryant on Instagram Monday night. James said he is, “Heartbroken and devastated,” at the loss of Kobe and his daughter Gianna. James and Bryant shared one last conversation early Sunday morning before the Lakers flew back to Los Angeles from Philadelphia. James passed Bryant for third place on the NBA’s all-time scoring list just the night before against the Sixers. LeBron and Kobe’s relationship goes back to when they first met when LeBron was just 15. A 20-year relationship that created a bond, a brotherhood and a connection as Lakers stars that will bind them forever. SI’s Robin Lundberg looks at the relationship between the two as friends and competitors, and how LeBron’s vow to continue Bryant’s legacy could manifest into an NBA title.
