This is how you throw alley-oop passes, but the passer has to have a decent pass/layup skill? And the reciever must be able to dunk properly... otherwise when you attempt an alley, it will go unanswered, or just result in a normal type pass.
To do alley-oop passes in My Player mode, i'm not 100% sure on... i'm assuming i'd be the same, but who knows. havn't had a palyer able to try it.
I haven't managed to get an off the glass oop to work yet. The only time my man ever caught the ball, Kenyon Martin stuffed me. --- "Well, I'm Nate Robinson from the Knicks." "OK, Nate Robinson from the Knicks, you're under arrest."
