Fouled at End

[Adam]

Watched most of the game (had to leave after the 1st OT) and thought the officials missed this one by giving him the bucket. The announcers were having a fit about the foul, though, assuming they didn't call it right away and insinuating that they made the call after they looked at the replay. They focused on the L and the fact that he did not signal a foul.
Watching the replay, though, it was clear and obvious that the C came in strong with a foul call immediately.
I don't quite understand why they gave him the basket if they didn't put time back on the clock. I can see giving him the bucket if they put .1 back on the clock; meaning the foul caused the clock to stop (or should have) at .1 second, so the horn should not have sounded.
I think they erred on one or the other.
