All of this on top of chemistry that will take time, lack of depth if they get Love (and trade 2-4 guys out), lack of proven playoff players and more specifically, role players, who can hit big shots and which every championship team seems to have (i.e., Battier, Allen), as well as, and I find this funny because it was a problem in Miami last season, age for certain guys (Mike Miller, Allen presuming they get him) who are now shells of their former selves, not only this coming year but going forward even worse. And this isn't even mentioning the fact that Chicago should be getting much better in the East and OKC and the Spurs are still out west. IMO, that's no shot.
The cherry on top going forward which I find hysterical is that if they get Love (which I think they will), he'll pretty much be maxed and they'll have a boatload of dough tied up in three guys, just like in Miami, only with two of those guys being mediocre defenders and their role players being far worse than when Miami was winning with Battier, Allen, and guys like Chalmers and Cole when they were playing solid in the post-season. And the talk again in a year or two will come to how Lebron still needs more guys around him.
At least this is how I see it playing out.
