I don't see how nikkas believe LeBron wouldn't have succeeded in the West. Unless dude went to a DOGshyt franchise (there's no franchises out West worse than the Cavs w/o LeBron), he could've at least went to two Finals. With the Lakers being down after Shaq and SAS making the Finals every other year, he still could've found a niche in the mid 2000s. Not to mention any season after the last Lakers title being up for grab.
He would've been in his athletic prime longer because of less minutes spent carrying the Cavs and their atrocious roster, so that would've led to a higher performance level from him. The West always had ballers over this time, so even if he went to someone like the Rockets in 08, he would've been balling with Yao, T-Mac, and THE Steve Francis. (that Rockets roster was actually pretty interesting, if they did have LeBron

)
There's no way Bron doesn't succeed, face it.
