Short Tights Or Compression Shorts ...

[HokiePaul]

I don't think this is that difficult. It says "Tights that extend below the knee are now legal."

So if he garment worn extends below the knee, then it would be tights and subject to the restrictions for arm sleeves, knee sleeves, lower leg sleeves and tights (black, white, beige or the predominant color of the uniform and same for teamates)

If the garment worn doesn't extend below the knee, then it is not legal as tights (call it whatever you want). But the garment worn could be legal as compression shorts if it is the predominant color of the uniform and does not extend below the pants.
