Try doing what i do, Get some friends together mainly experienced users. Get in a game (works better if you both have headsets) and lab certain plays. Find what works and what doesn't.
Check out the ncaastrategies.com forums. Alot of good info there. You may find someone to lab with pending on the defense you run. Some people say a pressure defense is worthless and pointless on this game, well i beg to differ. There are some blitzes that i can get pressure or tackle the qb in 2 or 3 seconds.
Some people call it a nano blitz, its close but i can only get it to work around 80% of the time, so its not really a nano. But i believe it to be close. A pressure defense really screws up a user's thinking, especially the ones that don't know awhole lot about football. Most users online only have around 1 though heading into the huddle or 1 main read. When you take away that read and have pressure in their face they will panic. Usually leading to a sack, yards loss or a turnover.
I love a pressure defense and i have a feeling it might even be better in the next game hoping they improve the defense. Not saying blitzing every down but in certain situations. One game i had, i totally took the guys RB out of the game. I shut his running game down and he had to leave his RB in for a blocker. It was awesome.
