i do alley-oops a LOT in the game...maybe 15 times a game, and it's an easy basket about 12 times or so. i play the bulls and hinrich is an excellent PG, with curry and chandler usually doing the finishing. i think the key is to be slightly off-center to the right of the 3pt line. get as close to the 3pt line as possible. if the guy in the post is not trying to box out but is instead just standing there (whether he's waving or not), hit the alley-oop button and it's an easy 2 pts. i can even get non-typical finishers like othella harrington and luol deng to complete alley-oops on a regular basis (i play on all-star).
but anyway, my question is regarding the 3 or so misses. when they miss, it's not b/c of a pass into the wing or the lob goes out of bounds. what happens is that the finisher will grab the lob and -- CLANG -- miss the dunk.

i'm thinking this is more a function of the finishing player's attributes (INSIDESC rating, maybe?) rather than the execution of the play itself b/c Tyson Chandler, for example, misses dunks more often than Eddy Curry, who almost never misses a dunk.
and then on fast breaks or just going strong to the hoop, players miss dunks too. in one recent game, my team must've had over 10 missed dunks. that's at least an extra 20 points that i should've got but didn't
any thoughts on why players miss dunks? is it a slider thing? is it a players.dbf attribute? or what???
