Well your first priority should be becoming more athletic because that's going to have the most effect. But until then you should add something special to your game. For example, become a 3 point specialist. Being able to shoot 3's like nothing will make you a real threat on the court. Or improve your handles to a point where you can cross people up even without your, yet to be aquired, athleticism! Maybe work on your defence so you become a wall that nobody can get around! A great defender stands out. However, like I said in the beginning, your first priority should be becoming quicker, faster, and stronger. Hope it helps.
