That's right... I totally forgot about that one. Go back and watch it... the Chargers player is so close that his knee touches Holliday's. If that's not an interference call, then there's no such thing.
Make that 4 inexplicable calls then:
1) Holliday's fumble non-call
2) Rivers' false start #1
3) Rivers' false start #2
4) Decker's phantom PI
