Unlockable: Hall of Fame Teams
In order to unlock the AFC/NFC Hall of Fame teams (like the Glaciers, Dummies, et cetera), you must complete the in-game Fantasy Challenge. To unlock these teams so you can play as them, you must beat them in Supreme League mode; otherwise, you will only get to play them, not as them.
Cheat: Three Players On One Team
In order to get three controllers aligned to the same team, do the following. Keep in mind that the 2nd player has to be using a wireless controller.
With all three controllers on, choose the same side with controllers one and two. During gameplay, press start on controller one and enter the menu. Turn the second controller off. Then, with the first controller, head to settings and controller setup. Slide the third controller to the same side. Go back to the start menu, and just before resuming gameplay, turn controller two back on (there should be a rumble on the second controller). Changes will come into effect after the first play.

Hint: Performance Institute Exploit
To increase your chosen character's statistics faster, hence making him a superstar more rapidly, try the following exploit. On gameday (Sunday), enter the Performance Institute and complete the exercise. After exiting, head over to your team's schedule and enter. Then, exit back out to the city map, and the Performance Institute exercise will appear again for you to use. You can do this over and over again if you want.
Hint: Draft Pick Franchise Building
Here's a great technique if you're looking to build a dynasty longterm over many seasons. It works best with "great" teams (like the Patriots, Colts and Chargers) and "good" teams (like the Jaguars, Broncos, and Cowboys). Theoretically, though, it can work with any team.
After finishing up your pre-season games, don't advance to the regular season. Instead, head to the trading block. Offer up your first round pick and ask for a first, second and fourth round pick in return. If your team is decent enough you will receive offers from all of the bottom teams (like Buffalo,Houston, Detroit, or whoever happens to be bad that season).
So, with the bad team's first, second and fourth picks (for instance), you can offer your own second, third and fourth picks. Ask for a first, third and fourth pick in return. You have to be flexible though, because you won't always be able to get what you want in return.
If the above works, however, you'll have two first round picks, a second round pick, a third round pick, and two fourth round picks (or something similar). This is absolutely amazing when you are building a franchise. Better yet, you can do this every year, as your franchise gets stronger and stronger with young, talented players.
