Hints & Tips

Easy Baskets in 24/7 mode
When you  are facing someone in 24/7 mode and are down 7-0, grab the ball and go up to the top of the key. You can either pump once, then shoot or drive past him going left. If you have the ball after you get the check, pump once, drive to either side, and make a layup.

Easy wins
Pause the game while playing, then go to the options and select "Gamesliders". While your there, you can max out your stats. Then, press Start to lower your opponents stats before you resume playing.

Easy skills and points in 24/7 mode
This trick needs two controllers for it to work. Now go to training for something like 3 pointers. When you start using both controllers, you will have control of your opponent. This will give you the chance to do as much training as you like. For the ratings, it will work the same way you will have the control of your opponent.
