This is a good play by Tamba Hali and a good example of disrupting the play even without sacking the quarterback.
Peyton Manning tries to go deep but can't step into the throw because Hali is rushing him. This causes Manning's throw to be short and incomplete on the deep pass to Reggie Wayne.
Chiefs defensive coordinator Romeo Crennel talked this week about disrupting the quarterback's play whether that's a hurry, knockdown, sack...whatever. This is a good example of Hali doing that.
