Here is a visual way to do it.  Imagine each blank is a player's position:

___  ___  ___  ___  kicker  ___  ___  ___  ___

The kicker position is taken, the other 8 can fit into the other spaces.

8 * 7 * 6 * 5 * 1(kicker) * 4 * 3 * 2 * 1 = 40,320 arrangements

Another way to do this is using a permutation - an ordered arrangement in which no objects can be repeated.

Use a permutation of 8 instead of 9 because the kicker position is already taken.

8! = 40,320 arrangements
