Did everyone figure out how to load a whole team at once? If not, please ask.
In 1973 and 83 there are a few players who are listed as "Utility" as their position. That's because the main position they played was DH. Those players are not eligible to appear on your final roster. As a reminder everyone's final roster must contain exactly ...
2 catchers
2 firstbasemen
2 secondbasemen
2 thirdbasemen
2 shortstops
5 outfielders
10 pitchers
That's players whose primary positions are as stated above.
If a guy has a primary position of 1B but also has ratings at 3B and OF, he can start at any of those positions, but on your final roster he will count as a 1B. Remember you need at least six players on your final roster from each of your four teams.
I know this is complicated. It's a complicated league for experienced owners.
