there was an old game for the super nintendo system called "nba give n' go" , I played it back then and I played it today a couple of hours and noticed that when you go to the basket and someone tries to contest your shot or block it you can press while in the air the shoot button again and the player goes up and under the other player and tries to do a nice circus shot with the glass

the game itself is realy ugly because its from 1994 I think but I played it for like an hour just to look at all those up and under's ... they were so sweet... imagine what will happen if it was in nba live

I also think this feature wont be so hard to implant, you just make that when you press the shot button one more time while in the air going for a layup or something it makes an up and under move.
also talking about it, where have all the regular layups disappeared???
all I see is those very wierd little finger rolls and stuff, why cant they put some regular layups to make it more realistic.
