Yeah, I have to be quick to change the coverage or the player I want to control.
Then again, I've had the AI take Delay of Game penalties where they could have snapped it easily, but don't for whatever reason.
I do use 25 sec accel clock, but I've seen the AI sit there for 5 sec and take a delay penalty while the next snap is in a second or two - strange.
That's usually an AWR it seems. The higher the AWR, the more likely they'll start throwing right when they sense they get hit (which makes sense - they want to get the pass off). I don't remember what Delhomme's AWR is, but I know for anyone over about 80-85 AWR - it can be annoying.
As far as the blocking goes, it might be suction pass blocking. I have CPU pass blocking at 10 and I see them get around blocking and when they do get engaged, it's a straight up contact it seems. I.e. they moved in position to pick up the defender, and I see free runners when I bring more guys.
I agree with dfos81 with the pass reaction. I used to play with it that low and hated it. I have it at 40 right now.
I do have my pass rushing at 30 and get about 2 sacks per game on average (which is about the NFL average), though the lower AWR guys and OL can cause me to rack up more. The most I had last season was like 9 on Matt Stafford (7 where CPU). It was insane. Of course stupid Calvin Johnson was equally annoying, but anyway...
If you're playing Normal, I'm a bit surprised you can't get more pressure with 64 pass rushing. I had it at that and it was like OMGWTFLOL pass rushing for both sides.
Slow - I could see it moreso. I would up it a little in that case along with increasing pass reaction time for human. I'm at 80 Pass rushing for slow, but that's probably too high (haven't played Slow in a while), but I think 70 would be good, especially if you lower CPU pass blocking some as well.
