Spiralicity is a measure of two factors: how tight the spiral of a thrown football is, and how rapid the rotation rate of the football is. When the tightness (lack of wobble) and the speed of the rotation are considered together, the spiralicity of the pass can be gaged.
Michael Vick's passes never were known for their spiralicity, but ever since he got convicted of that dog fighting hog mount I think his passes are even uglier. In a way it doesn't matter because after that I quit watching him play, DTLOI.
