Is there any evidence that Lebron takes PeDs? Him still playing at an MVP level at age 33 is not, in and of itself evidence of PeD use.
This is uncomfortable for everyone to talk about, but we should. Honestly I'm surprised how much benefit of the doubt people are eager to give Lebron, and athletes in general.
You are right that there is no hard physical evidence that Lebron (or anyone currently playing in the league) is cheating. There is only circumstantial evidence. But there is a lot.
1)
The NBA drug testing program is extremely easy to game. I think this is intentional.
2)
Lebron is appreciably more athletic, more explosive, stronger, bigger, and muscular than he was at age 25, typically the peak of a man's testosterone levels. This should make sense, given that doping can have a cumulative effect over time. (If your instinct is to scoff at this, just watch highlights of game 7 of the ECF against the Celtics in 2010, which is considered one of the more brilliant games of his early career. He was appreciably less muscular and explosive back then.) Heck, if you ask me he's bigger and more explosive now than he was just one or two years ago.
3)
Lebron has played 15 years in the league already, just led the entire league in minutes played in the regular season, has played about 100 more playoff minutes than anyone else this year, and is still consistently the most explosive guy on the court at age 33. He also virtually never gets injured, and when he does he heals quickly. It's possible that "he's just a freak" or "he's so smart he knows when to rest during games", but honestly I think those explanations are less likely that the obvious one.
4)
His face has clearly changed over time in a way that doesn't look like normal aging. Again, this is uncomfortable to talk about and there is no smoking gun, but we know that there is something called acromegaly related to prolonged HGH use.
This is all circumstantial. I get it. And again, there is no doubt that other players are likely using. There are probably guys on the Celtics that are using. But Lebron's case is truly unique, because he has almost singlehandedly changed the course of NBA history. His teams have won the Eastern Conference for 8 straight years and he's now considered an all-time great. I already feel extremely conflicted about this, and I for me at least it has made being a basketball fan less enjoyable. I would probably feel even more conflicted if he were on my team. And I suspect that this whole thing won't end up well for him, either a couple years from now or 20 years from now, in which case I'm not sure I want the Boston Celtics associated with that.
