The 12/12 was from the free throw line, I don't think he hit 12 free throws total for the rest of his career.
I just watched it, very well done. The credit Shaquille gives to LSU is an outstanding reflection upon the university.
Arkansas had to triple team him, and consistently put him on the foul line. Even with that stacked team they had with Todd Day, Oliver Miller, and Lee Mayberry.
