Just before the end of the1st half there were a series of plays that, IMO, really shifted momentum:
The Play starts at about 2:03 on the 50...Chargers @ 3rd & 4 and Von gets a sack for about -14 yards
Punt is blocked by Irving
Manning hits Stokes for a TD.
All these plays happened one after another and are illustrative of all 3 phases working together. I need not point out the difference of getting a sack on 1st contrasted to 3rd down as you all know what it means...But to follow that up with a great ST Play and a TD by the Offense is very good FootBall.
