Basketball Ground How Steep Can A Driveway Be For An In Ground Basketball Hoop?

How steep can a driveway be for an in ground basketball hoop? - basketball ground

I have three garage entrance would be the size of a spot in the basketball hoop perfectly on one side. The problem is that it has a slight slope and not a completely flat surface, and I fear that have flat or nearly flat for such a ring. Does anyone know the maximum gradient must have an entry for a ring in basketball have? No experience with one on a sloping street? Thank you>
