-If anyone actually thought it was a "big 3" with all parts equal, then no, it's not to early to call Bosh a "Bust." Bosh being considered a similar talent to Wade/James was always laughable, in my opinion; I thought Bosh's biggest and greatest PR self-promotion move was to make sure he got his name thrown into the 2010 free agent discussion riding on Wade/James/Amare coattails. I always thought he was soft, a high-volume, high-minute, decent but not too efficient player, like an abdur-rahim in his prime type.
-Yes, it's too early to assume he's going to be a low-percentage, poor-rebounder for the whole tenure of the Miami Threet.
-However, considering that the heat have looked quite scary so far in certain moments despite at the same time looking discombobulated, and considering that James only went to miami because it was definitely going to be Wade AND Bosh he joined, no, he's not a bust at all.
(in other words, since having bosh was key to getting James, Bosh can't be a bust...think of it this way: would miami or any other team pay 32 million instead of 16 million to be the one to get James if they were allowed to? Yes. Definitely. So Miami payed 32 million to pair James with Wade and got Bosh to tag along too. No bust in the big picture).
