Call a Hail Mary in a Shotgun formation and call a special team's field goal block for the defense. Now get rid of the ball quickly and you can walk in to the endzone with your WR and you will get 48 points per play. NOTE: You must play every time you do training camp without simulating it to get a boost for your player.

This is a legit tip. It's cheezy but it does what it says it's supposed to do. It actually works even better you reset your play level at Rookie. You can always reset your level of play back to one of the higher levels when gameday hits. FYI The game says 10 games is the minimum number of times required to play to get the Superstar rated/upgraded for that instance of practice.

Some players demand a lot of money. One trick is to sign a very low paid player in free agency. Change his position to the position of a player you want to have pay less (the player you want to keep must already be on your team).

Take the highly paid player and change him to a position that he would most likely suck at (i.e., change Andre Davis to a HB). Re-sign this player at his new position if his stats are worse and you should save a bundle of money. Then simply change him back and repeat this trick with as many players as you want. This does not always work however, some player may still want more money. All positions can be done with the exception of QB's, K's and P's.

When you have an agent that you can go to the Performance Institute, go in, but you have to do it on game day, the same day you have a game, (might work even on a practice day, or a day without any events, I haven't tired it yet) but do it before the game of course, do your practice, gain the points to go on your attributes, add them, then when you exit, and the autosave comes up, save your superstar season, then go back to the calendar (you have to go to the calendar first) then go back out to the map.

Go the the Performance Institute again and you'll beable to do the practices again that gain you points, do it again and the previous points you got will still be on your attributes and you'll be able to add the ones you gain from the pratice you just completed. You can do it over and over till your attributes are maxed out.
