Only one of those passes was actually under thrown. The under thrown ball to Harris was, in fact, under thrown. However, it was within his catch radius. Harris just wasn't ready for the ball. The "under thrown" ball to Custis was more or less thrown perfectly. He turned around for the ball--as he was being held like a boss--and it hit him in the chest. The "under thrown" ball resulting in an interception wasn't under thrown. DeVito bit on a well disguised coverage. In his defense, I bit watching that coverage.
