In NFLRZ in order to get easy money or gameballs is to find a "hidden" football. Well, this glitch allows you to go to the same menu that you would if you clicked on that football.
1) Log in to NFLRZ
2) Copy and paste this link: http://nflrz.nflrush.com/play/discovery
3) The prize menu will come up, as it would if you found a football
4) Simply select a prize
5) Click the back button on the menu
6) BUT, it just refreshed the prize menu!
7) You can keep doing this as long as you want, and it ALWAYS works!
8) When your done, look above that menu and notice you'll have a mini-menu, select anything on that to get out of the menu.
