It is obvious that both Trent Green and Kevin Harlan are basically the home broadcasters for the Chiefs (both reside in KC, and I believe Harlan was the radio voice for them before going to CBS full time).
Lookin' like the refs are the chefs home refs too. That was pass interference! Plus the defender took 2 or 3 steps and pushed Mills to the ground late! No call either place! grrr!
