There has been live feed showing of BB7 lately which shows Sam absolutely did back stab. They edited it out and put the blame on one small thing Grace did.

My theory as to why? The producers don't think Sam would have been able to handle the negative reception she would have got has they shown the extent she had backstabbed Lea and Richard.

With regards to the question, the series would have gone to pot and lost one of the very best housemates
