If you watch the play live you can clearly see at around 4:00 of the video the LDE bull-rushes Colon straight back about 5 yards then jumps with his arm extended right beside Ben causing him to pump. The DB was sprinting up to tackle Holmes when Holmes snatches the ball out of the air and changes his running direction in a 'C' toward the sideline so the dude was out of control trying to close on Holmes and slipped trying to stop.

Moore was standing on the 47 yard line on the pump fake and the DB that slipped was on the 31 at the time of the slip.
