yeah. I use those. Even though its created for the patches, it works well without the patches. Running is alot tougher to stop.
The most notable difference between patched vs non-patched is the CPU D. Alot of the complaints when the game came out was defenders cutting off the receivers and "knowing" the routes. I have only found this to be true if I am running the same play multiple times in the game within a short time span. No longer will you be able to throw a deep post over the middle 100% of the time and vice versa. Your cpu D should play alot better with coverage and the middle of the field shoudlnt be wide open 100% of the itme. Also, you can run zone D and IT WORKS!
ANother big thing is that the QB will actually scramble. If nothing is open, they will tuck the ball and run.
