actually there is. When you see a real life shot go straight into the basket without it touching the net. That's a perfect shot release. When you see/hear the net snap as the ball goes in without it even touching the rim. It's a perfect release. Shooters have different green release areas in real life, depending on how they shoot the shot they are shooting. I'll give you an example. when i used to play a ton of basketball. I had 3 different shots. I had a shot when or if I was injured and coudnt get off the ground as well as i should for my normal shot that was shot that started on my right side but really low and pushed off of my shoulder almost. I had it down to the point it was a swish a lot of times. the only problem was, it was hard as hell to shoot like that on the move. it was great for a catch and shoot situation if i was injured. and if you did anything wrong that shot would be all over the place. very difficult to rebound/soften up said shot because it had a crazy arc. but it was MONEY when it hit. didnt touch the rim.
^green release
2nd shot when I was healthy but I'm shooting from a far distance (true nba range or deeper for a game winner or end of qtr shot.) Still good lift on the jump but also kind of holding the ball above my head for that extra added strength since I wasnt use to shooting from that far out( i aint no nba player. lol.) but when it hit money. it was all net. GREEN release.
3rd shot. was my normal shot from mid range or college/high school 3. shot was released at my forehead with good lift on it. when it hit that net with that snap and the ball would land and roll back towards me. I knew that was a perfect release. GREEN release.
So yes even one person could have 3 different shots with 3 different green release points. therefore other people would have other green release points in their various shots. If a defender is on you but you need to get it up and over him. and you release it later, if you put the right amt of arm strength/wrist flick. you could still get a green/perfect release. but its hard as hell to pull off since you need to find your balance mid air while also avoiding a shot blocker while still concentrating. thats very hard to do in real life. This can be simulated in the game if they made you have to straighten up your shot trajectory as well as straighten up/balance your body and they make the balancing speed different for different archetypes as well as different for different sizes of guys.
Dont get caught up in the idea of a green release needing to be nerfed. it doesnt. the entire mechanics of shooting need to be re-worked to be more realistic. Ray allen in practice probably hits a lot of perfectly released jumpers. same with JJ reddick. so never say green releases are not possible unless you're a robot. its not true. they are possible. but they are extremely difficult to pull off due to all that stuff that goes into it as i suggested above.
