Exactly. Not only that, replace LeBron with any other player in the league, give him the same supporting cast. How does the team fare against Golden State? How many games would they win in the regular season? (I go 30-35)
And all the idiots who think the game has somehow regressed never seem to have an explanation for why that would be. The money is greater than ever, meaning the motivation to succeed is huge. The talent pool is bigger than ever, and now pretty much spans the entire world. Training and diet are better than ever. Scouting is better than ever. On what logical basis do players somehow get worse under those circumstances? You may have special cases, elite guys who don't come around often (Shaq, Jordan, etc), and aren't easily replaceable, but to think that the ability level of players as a whole is somehow getting worse is some kind of magical fairy dust thinking totally removed from reality.
The game is different. It evolves. Every sport does. You may like older, different versions of the game more, but unless you get into a situation where there's a logical reason to think that the talent pool is getting shallower (see boxing for something like that. Basketball is actually the exact opposite), it's moronic to think that players are getting worse.
