We see it every week, Beast runs for 3 yards a carry in the first quarter, 4 yards per carry in the the second and then 7 in the 3rd. By the fourth quarter there is a very real possibility of 30 yard sprint to the endzone. The opposing defense simply wears down and this doesn't happen by accident, it's part of the game plan and the entire offense is part of it. RW's scrambles don't just buy time for big plays, they wear out the defensive line, linebackers and secondary. All those go routes run by our WR's have the same effect on the secondary. In short, this offense is built for the fourth quarter. Now factor in Percy Harvin, a player with explosive speed and agility. Percy is going to get the ball out of the backfield in the fourth quarter of the Super Bowl and he is going run right through a tired Denver defense....you can bank on it. Go Hawks!
