How late is too late??

[rainmaker]

Too late is too late. It's a tough call, and no doubt about it. I'd say in your situation, once the dribbler had turned, it was too late.

The trick to getting this call right is A1's "ability to play through". Sounds like there was the ability there, and B2 just took advantage of a "fumble". Whether or not to have called the bump originally would probably depend on the level of play, and the overall style of the game, and what else was being called. You probably got it right by not calling it.
