Headscratchers in what way? They may not have been as "dumb", but they looked like fouls to me. The first one was obviously a push-off, and he needs to be careful of that stuff when he is around a flopper like Bibby. And the third one may or may not have been a foul, but he got in under the guy on the rebounding motion. Again, may not have been something he could have avoided, but it wasn't NOT a foul.
Headscratchers in that they were awful calls. If you are going to be calling those fouls, then there should be fouls called on every single rebound. Rondo should take time in the heat of the moment to realize he is around floppers like James Jones and Bibby? I don't think that is a reasonable request.
