You can play your games, pause at all stops, and praise the unhappy player. Or you can call other players who do not have great team relationships. Perhaps, there was an incident report about two players. If there is no incident report Calling a player can be helpful if he is friendlier and has a higher coach relationship.
I have also noticed that if there are two freshman at the same position it is more difficult to maintain coach and team relationships for those players. I agree though, in the future it would be nice to see positive options when calling a player.
