It might be a good time to see some stats regarding key numbers in the NFL. We all know that 3 is the biggest key number but 7,6, and 4 are also key numbers that often come into play. Since -6,-6 1/2 and -7 are all numbers that can be readily attained right now..... perhaps an updating of likelyhood of them coming into play might be timely. Does someone here have the exact numbers ?
