Why didn't Ben Listen?

As you will see in my previous post, Peter King, football writer for SI.com, said one of the reasons Pittsburgh would win was because Ben Roethlisberger would not play like he was 23. I'm guessing he meant Ben would play at a greater level than would be expected of a quarterback with only two years experience on the NFL level. However, I cautioned Ben against playing like he was 31. Alas, Ben did not heed my warning and proceeded to throw 2 interceptions in Super Bowl XL.
