I will agree it was ridiculous only because there were clear differences in the fouls. Clingan made a basketball move, and only Clingan will know if it was intentional, but it appeared to me it was not intentional done to injure Jones, just Clingan is so big compared to the defender that unfortunately Jones' head was at the height of Clingan's turning elbow. By letter of the law it is a flagrant 1 though.
With that said, Jones' elbow was not a basketball move and the only intent was to hurt Clingan. They should have been assessed differently by the refs.
