"I don't win my championships in Miami without him," James said. "What he meant to that team, all those years that he was down there in Miami—when I was there, my four years, and even a couple of years when I was gone—he's just a true definition of what a professional is all about."
James spent four years with Bosh in Miami from 2010-14, winning two titles in four NBA Finals appearances alongside Dwyane Wade.
Bosh continued to thrive once James went back to the Cleveland Cavaliers, earning All-Star selections in 2014-15 and 2015-16 before health problems forced him to retire.
In six seasons with the Heat, Bosh averaged 18.0 points and 7.3 rebounds while being named an All-Star every year.
Although he was sometimes overlooked next to James and Wade, Bosh made a big impact for some elite teams.
