Instead of bad passes coming out of nowhere like they do in this game I think EA should implement something along the lines of this:
Everyone knows that in Madden you can use Peyton Manning or Shaun Hill and get similar QB play if you're controlling them. They have stretched out the ratings to make more of a difference between good and bad QB's but sometimes you will get a perfect game from a bad QB with random bad passes here and there with no distiction of when a bad is coming.
SO.....
Whenever a you're going to throw to an open man a pro QB will always hit them.
BUT whenever Manning throws that deep out, with tight coverage, before the WR breaks it off to time it out perfectly Manning usually makes a nice throw. If Shaun Hill tries to make that same throw he'll probably lead the WR too much because he's not as talented enough to make that throw.
SO in Madden whenver you're throwing into tight coverage a bad QB should either make the throw or overthrow the receiver because he has less confidence. But in Madden now you never expect when your bad QB is gonna throw a bad pass, it's usually pretty random.
I hope this makes sense...
