Well, according to what he told David Aldridge that he wants to play in Rio:
No, I’m not officially in, just yet. But hopefully, I can be healthy enough and on top of my game at that point where I’ll be taken.
If he plays, he will be the first American player to play in 4 Olympics. He will make the team if he plays, but he may be looking at a whole new supporting cast. You can probably rule out Chris Paul, Carmelo Anthony, and Kobe Bryant. You will likely see Blake Griffin, Paul George, and Kyrie Irving instead. The USA is stacked with young talent, and they will be the favorites for many years to come.
It will strictly be up to Lebron whether he plays or not. By the time 2016 rolls around, Lebron will have a lot of mileage on his body. He plays in the playoffs every year, and that’s a lot of minutes for a guy to play. It’s been a blessing to both him and the NBA that he has remained healthy throughout his career. We will see if Lebron dons the USA jersey again, but you have to respect a guy who wants to represent his country.
