I supported BC until this this summer. But a number of wrong moves followed:
Not resolving JJ issues and giving him up. (He might have TOs in Sacramento now, but a lot of it has to do with new players. He showed a remarkable improvement last season and would've been boss for us this season)
Going after Nash. A short term fix and deviating from the path.
A subsequent result of that - Fields, despite how many times BC can say, he wanted Fields anyway.
Sticking with AB, which now overweighs the positives.
If BC goes, so will AB and that's a good thing. Otherwise, there's not a lot a Toronto GM can do, given how things relate in the NBA.
