1.) Shot inside is under the basket. or just around it, it doesn't really effect layups, because layups are in-motion moves, like driving to the basket, or a fast break.
2.) This is different because its in the paint, further away from the "inside" type shot. This is more of a hook shot, or a tear drop.
3.) This is getting close to the basket, but posting up. like Dwight Howard backing in, then turning and slamming.
4.) Layups are an in-motion shot, like blowing past a defender, or a fastbreak.
5.) Like layups, dunks are in motion too. The skill for dunking, is for literally the skill of how good you are at actually putting your hand in the rim, and dunking it. Standing dunk is aside from that, very useful in a center position. Catch, power dribble, and (standing) dunk. Upgrade that.
6.) You'll need this too. 90% of the time you're down-low, you're gonna have traffic on you, not just your defender.
7.) This is for shooters. Drift shots, catch-dribble-shoot type shots. you wont need it.
8.) This effects the types of dribble moves your guy can do. you're going to want "Ball Security" so you don't get stripped.
9.) Hands is catch, and ball security is keeping it.
10.) Backing down in the post.
11.) Defending in the post.
12.) Not really.. this is more of a LeBron guarding Rondo scenario.
13.) It could help. Its like a difference between Shaq, and Dwight. Dwight's quicker. It'll help. FAST DON'T LIE. Haha
14.) Big time, and backing down.
15.) Not a whole lot. Experiment in practice mode with Shaq and Dwight and see how that goes.
16.) I'm in my 2nd, i have no idea how much further..
17.) Haha, I don't know that one either.
18.) Pass a lot to the outside shooters, or the PF nearby.
Hope this helps,
