Now I am doing those things and its simply by diving at the quarterback.
Maybe a lot of you do this already and this might not help you but it has made this game more fun for me.
I use DE or DT and use the stick at the line but when I break free towards the quarterback I hit square to dive at the quarterback and have been getting a lot more sacks. If you dive too early then you screwed yourself out of the play. You dive at the feet of the QB and he will fall, or if you're closer, you will dive at his body for a hard hit (very satisfying). I found that diving at the QB will result in much less of those plays where you could swear you're about to get a sack but the QB manages to throw the ball away. Those situations are sacks now.
Here is an example:

QB is about to release the ball as I dive and take his legs out. SACK!
Probably wouldn't have got to him otherwise.

Again, as Palmer was about to release, I dive and get the big sack. Good solid hit on the QB.
Both of these situations would have probably resulted in an incomplete pass if not for diving.
Play the game how you want, but if you are having difficulty with getting sacks... this works.
