There are no details, for a little over a year I tested Madden, NCAA and other EA games at their new facility in Baton Rouge (the one that caused half of the Orlando office to lose their jobs). I was a Database Manager so I worked as a liaison between our floor testers and the developers.
The developers were either huge dicks who would not listen to you, or complete morons. Very little variance between those two extremes. A lot of Tiburon's employees, including upper management, were literally bagging groceries or delivering pizzas before they joined EA as testers and worked their way up. I was amazed at how few of my superiors had college degrees. (Though to be fair that's more on the QA side than dev.) The other ones are your typical programming geeks who have no idea how football works. So you have a hybrid company of technically oriented geeks and complete morons who have no business qualifications or leadership skills.
The devs at Tib are either too arrogant to listen to the testers' input or too lazy/useless/incompetent to implement any real change. "Yep, we can ship with that" is the only thing a developer ever wants to say about any gameplay issues that come up.
As long as it doesn't crash the game or cause it to fail Sony/Microsoft/ESRB inspection, they are fine with shipping it.
