I normally use an 85 f/1.8 for BB, a 50 would be ok, but anything less is way too short.
I've seen excellent shots taken of players driving for a dunk or layup from under that basket with wide lenses. These shots will usually show the offensive player going up, a defender trying to block and a dynamic view of the arena.
If the OP knows he wants a wide lens then I don't question that. All sports would be shot wide angle if we could only get close enough in most cases. I think telephoto is a make do solution.
