As I thought about the value of the draftees in Franchise (which is what I am calling my "fantasy sports game" for now), I realized that their values were fairly cut-and-dry. While the offense and defense ratings provide a need for both attributes, it's pretty clear that a draftee with a rating of 6 in either category is always going to be a better choice than a 3/3 draftee.
The stat adjustment cards and the mandatory loss of a stamina token at the end of each season were created to make the value of a draftee more dynamic. However, this doesn't affect the first draft, and the value of the draftee is still basically the same for all players.
In order to make the first draft more interesting, the draftees will be displayed in 3 rows, with the number of draftees in each row being one more than the number of players. In the first row, the draftees have 3 stamina tokens; in the second, 2; in the third, 3. This would only apply to the first draft, and would create the same dynamic that you would get in subsequent drafts. For the subsequent drafts, the new draftees would start with 3 stamina tokens.
To create situational value, the draftees would have another attribute -- a classification of sorts. If two draftees on a single team had the same classification, they would each receive some sort of stat bonus. I haven't quite decided what the classification or bonus should be. For classification, I was thinking of something along the lines of nationality, play-style, or some generic "chemistry" value. One idea for bonuses would be that if the defender and midfielder shared the same classification, they would increase their defense attribute by one; if the forward and midfielder share the same classification, they would increase their offense attribute by one. A more simple version would be to increase the consistency attribute of any player that shared a classification with another player on their team, even increasing it by the number of players that it is share with (i.e., as many as +2).
This classification makes individual draftees more attractive to players that already have a draftee with that classification on their team. This situational value is key to making the auctioning more interesting, so that players have to be more careful about bidding an opponent up.
