I believe some players with really small sample sizes aren't correctly utilized defensively by the software.

This used to happen with CF, but I believe was fixed. It might not have been fixed at other positions.

This leaves two choices:

1) Be happy or sad that this player does better at that position. It is usually only a one time thing, and would usually not be the reason a team makes it to the playoffs.

2) Let Mike know before the season that certain players may have defensive statistical problems (I.E. Glaus) and he may be able to look at this and fix, or make some type of temporary solution.
