Position eligibility check screen.
Have a My Team option, so you don't have to check all of your players individually.
Regardless of the percentages, if you have rookies or players that are getting a try out at new positions, or Anthony Rizzo, it would streamline the process. I understand the positions are next to the names, I see that. Just one click and done, just to see if a player on your team may become eligible at a position, to help better determine who you should add or drop. That's all.
Can you explain why you feel this would be helpful? The players have the positions listed next to their names on every page. The number of players becoming eligible for new positions is a very small percentage of the player pool.
