It’s crazy that with John wall’s retirement Paul George is now the last man standing from the 2010 draft class. It makes it really hard to believe that LeBron James is still playing and was a member of the 2003 draft class. That guy really is in his own category. Absolutely amazing lifelong commitment to fitness.
LBJ isn't doing some Podcasts that's why he lots of time to maintain his health unlike PG13 where he focused more on Podcasts rather than his health last season that's why he played less than half of the total regular season games. 
Kidding aside, it's only a matter of time until PG will retire as well. The Sixers made a huge mistake by giving him a max contract only to play like that in his first season with that team. If he'll be doing the same, I will not be surprised if the Sixers will buyout his contract and there will be no more team that will be interested on him hence, retiring might play overseas. Lebron is on a different dimension when it comes to health. Imagine a 40 year old player averaging all-star stats still. We haven't seen anything like that that's why the NBA will be different as soon as he retires that's for sure.
As for John Wall, he's another victim by "Great career ruined by injuries". He had a superb career back when he's still in Washington and he and Beal carried that team to the playoffs as well until injuries came. Anyway, congratulations still to him.
