Don't you just love surprises?
OK, one's answer to that question depends entirely upon perspective.

Did we know the Cardinal's defensive line was good? Yes. Did we know it was that good? No.
Almost a month into the 2012 season, such unit surprises have been plentiful. Some, such as Stanford's defense, have been mild. Others, such as USC's offensive line, have been shockers. But which of the surprise units could have the biggest impact on the national scene?
With that in mind, I present this week's edition of the top-five list. It's a quintet of surprisingly good positional units that could alter the BCS picture.
