Here is my initial design idea for your consideration: #14. Part bball and part hip/urban. I will post a flat version for print onto jerseys next, just so you can see how that would look!
Here are potential flat color versions, which show exactly how it could look on shirts, jerseys, etc. #15, #16, #17
I also added a grunge/distressed layer over the top to give it a cool vintage feel. The grunge texture is on its own layer, so we can turn it on and off as you please!
Here is another idea with a "B" on the basketball: #18, and then you can remove the words and have just the ball as an alternate icon of sorts! --> #19
