Computer kicks
Whenever setting up for a kickoff, field goal, or punt, push the B button to change players. This will leave the computer to control the kicker, leaving you with an almost perfect kick everytime.

Better Created Players For RB, FB, TE, & WR
When ever you are creating a player do not worry so much about the pass or run block, drop the run and pass block down to zero, and fill up the rest of the stats you want, then if you still have points left fill the run or pass block up as you want. (P.S - even if your run and pass block is at zero it will still be 100 %) Unless you are making a FB you might want to put the run block better then the pass. And if you are making a tight end you might want to keep the pass block better then run. (P.S - It is impossible to create a perfect TE , but if you use this method of playing he will have pretty nice stats.)
