When I get home from work tonight, I'm definitely going to try and get a little more "brains" into both the Human and CPU defenses. I don't want to go to high, because there is a fine line between players playing to their Awareness rating and players playing like they're all smart.
One of the things I like about Pro level is when I'm playing my Franchise and I look at the scouting report for the upcoming game. I read through everyone's scouting report, position by position, and try to exploit the other team's weaknesses. If I read in the scouting report that one of their players isn't great at recognizing plays, then when I'm on offence, I look to exploit that player by trying to get him in mis-matches and running alot of play action passes and draws to his part of the field.
If the Awareness slider is too high, this gets thrown out the window and everyone plays very brainy. That's why I found 13 to be a good number, but after playing Slthree's sliders last night, one of the things I liked with his MAXED CPU Awareness slider is that playing offence was a grind. I don't think I'm going to take it to MAX, but I'm going to try and make the CPU play smarter without eliminating the possibilty of PA passes and draw runs.
One other thing I noticed if the CPU Awareness is too high is that the running game for the User becomes a "feast or famine" situation, where either you gain alot of yards or get stuffed for next to nothing...or worse. It's because the CPU Awareness is MAXED so the defence is in your backfield almost instantly because they automatically know that it's a run and where it's supposed to go.
I'm constantly tweaking, but haven't come up with anything noticeably better than the sliders I posted on page 1 of this thread. Everyone will have to make minor tweaks to suit their individual styles, but I think what Slthree and I have come up with is a set that will suit you about 95%, and you'll have to tweak them to get that extra 5%.
On a side note: I'm pretty close to completing a Varsity level (equivalent of Pro in Madden) set for NCAA 07 on the current gen systems. Look for those soon, if you're interested. My early work has me very encouraged, and I believe that NCAA will actually play better on Varsity than Madden does on Pro.
