No chance in hell. There is absolutely NO WAY any ONE PERSON could find EVERY glitch/flaw/GAMEBREAKER in any video game.
The best way to put it is this: EA staff's somewhere around 20-25 Quality Assurance people per video game. I don't care how much time those 20-25 people spend playing the game, they will NEVER be able to find the number of glitches that the HUNDREDS OF THOUSANDS of us will find within a week after the game is released. It's purely a numbers thing, folks.
With that said, I would hardly consider this bug/glitch/whatever the hell you wanna call it a GAMEBREAKER.
As someone posted earlier, the way around it is audibles.
That, plus think of it like this. If you were standing in a batters box and I was pitching to you, and I was TELLING you what pitch was coming, you still gotta be able to hit it. Just because I tell you a slider is coming doesn't mean you're going to be able to make contact.
The same can be said with this game. Just because you know a run or a pass is coming, it doesn't mean you're automatically going to be able to stop it. Hell, most of the time you can tell whether a run or pass is coming simply by looking at the down and distance ANYWAY!
Relax, folks! Stop being a bunch of damn Chicken Littles. The sky is not falling! This game is still better than last year's, and I'm sure EA is already hard at work on a fix anyway.
