whatever the fans say, BC is a good GM. He's just not good for us, or for any rebuilding team. You need patience in that role, and all signs point to BC having none. He rushed the process in the 2006, in 2009, 2010 and again in 2012. The moves themselves were mostly good, but the timing was poor.
Just imagine a few alternative histories:
2006 - rather than bring in all that talent, what if we tanked that season, traded CV for a pick and maybe won the lottery, we could have had oden/durant AND another top 10 pick maybe (for CV) in a draft that has a ton of great talent.
2010 - after Bosh
leaves, we don't sign amir/kleiza and the rest. Instead, we tank harder for two years and maybe get one of irving/davis. If Bargnani
plays like he did in 2010, you trade him after the season for a pick and we could now have at least one much better pick than ross + tons of free cap space.
2012 - no fields, no lowry, trade andrea at his peak etc
every chance he got, he chose the shortcut ... maybe we'll give him another chance in 4-5 years, but for the time being, he needs to go.
