What does Rose have to do with Miami beating OKC in the Finals? If you're saying that Miami wouldn't have had a chance to play OKC in the Finals because Chicago with a healthy Rose would have beaten Miami in the East Finals, that's completely misguided conjecture. Miami beat Chicago in the East Finals the year before (Rose's MVP season) 4-1 with LeBron guarding Rose most of the series, and doing a damn fine job at it. Now, that doesn't necessarily mean that Miami would have beaten them again, it just means it's delusional to assume they wouldn't have when they were obviously a better team than they were when they beat Chicago 4-1.
You do realize that the Harden trade happened after Miami beat OKC in the Finals, right? The "star count" was 3 vs 3.
Huh. That's news to me.
That doesn't seem anywhere near the type of drop as plenty of other hyped players coming into the league. Greg Oden was often referred to as a modern day Bill Russell and the dude has barely even played 82 games in his entire career. That's just one example.
You can argue that LeBron was over hyped (the expectations couldn't have been higher), but to call him the most over hyped player of all time? Pure hyperbole in a discussion that has no way of proving said claim in a quantifiable manner in the first place.
