This is something that I have noticed as well...and what bothers me is these guys will throw 1 inaccurate pass,or the cpu will do the same,and these guys will say "see inaccurate passes are in the game"...
I'm also not seeing alot of this "improved defense" either...it seems like crossing routes are pretty much money...so that would also lend itself to open slants as well.
The only hope I have is that since I only play offline CFM,this stuff can be corrected by slider adjustments....providing they work better this year.
My last issue,is the lack of penalties....I have read on the forum here that folks are sick of the penalties in the preseason games,and while I admit there have been LOTS of penalties....but the constant I heard is "simulation"....that is what EA has been touting.
While there are some things that have looked improved,I don't believe that you can tout "simulation" when penalties don't even work properly.
