With Logitech Wingman Rumblepad??!!

Hi...

I have a Wingman Rumblepad, and when playing the dunk contest i can only make the same 20-25 dunks every time i try.
I mean, I make combinations with the four bottoms, starting in differents places of the court, making alley opp or not, moving in circles the left analog stick or not.. that is (if my Maths skill is not bad hehehe) around 20-25 combinations.
But i can't still do some combos that the CPU usually makes. In example, i cannot put my elbow on the ring and a lot more... Is there something i'm missing? another bottom i have to use??

Thanks everyone!

well, it's not the controllers fault, i have the same one and everything is just

find the dunk combinations thread and learn the dunks you can't do...

Thanks man
