I have probably 5 or 6 plays like this saved on my PS3 where the QB throws a ball and it knuckles like a Tim Wakefield pitch in mid-air. This is the wire view so it follows the football, and you can see the camera suddenly changes direction. This is why I've always believed the game is, to a point, scripted. I should have an interception on this play, but the ball just knuckles around me.

As for blocked punts, the game considering them a fumble causes a few problems. I block this punt, and the punter recovers, he can in theory, pick the ball up and run...and he could've run 10 yards maybe in this play. That's a big deal. Even if this were a fumble, the rule is incorrect. For the most part, you guys have the 4th down thing correct, that it can't be advanced, but it can if it's by the player who fumbled. Maybe you guys know that rule, but I think the fumble actually is attributed to the center if I'm not mistaken and that causes the kicker not to be able to advance. Similarly, missed FG returns are counted as fumbles then those are not either.

Lastly, part of me believing it's scripted, is stuff like this.

I can't tell you how many pics I have on my cell phone or saved on the PS3 of the ball going THROUGH my players body. Sometimes the helmet, sometimes the arm, sometimes the sternum. It doesn't always happen though, which makes me wonder why it happens when it does and if it happens to help the AI, because the ball has never gone through the CPU to help me.
