Question

5) The diagram below shows the point value of having the ball on each yard line. It is taken from Romer's "It's fourth and two." 4 10 20 30 40 50 40 30 20 100 Yard Line -1 -2 -3 b)If you have the ball on your own 10 and gain 30 yards, how many points have you gained n expected value (Remember that my "own" side of the field is on the left hand side of the horizontal axis)? Please also write out the equation for your calculation. c) If you have the ball on the 50 and fumble, and your opponent recovers the ball at the same ard line, how many points have you lost in expected value?

Explanation / Answer

a) It's around 2 points

b) As one's own side of the field is on the left side of the horizontal axis,so onw will start at around -0.25 value and keep increasing his value to about 1.25,so one would have gained 1.25-(-0.25) = 1.5 points.

c) The value of the opponent having the ball on the 50 yard line is the negative of one's value of having the ball on the 50 yard line.So,one would go from a value of around 2 points to a value of -2 points in which case he would lose 2-(-2) = 4 points.
