What number belongs in the spot with the question mark below (and why)?

  1   2   3   4   5   6   7   8   9  10
  0   1   1   1   1   3   2   4   4   ?

Looking at the numbers it happened that no ideia came to my head. Then I looked at the title of the problem and... voilla! Those are the number of ways to make N points in american football.
That means the answer we are searching for is 5.
