I've had similar problems with one of my trainees,
(30656464), although usually I only lose 1-2 minutes because of it. But it's happened the past three weeks or so and a couple of other times throughout the season as well. I think it's a combination of just bad luck with subbing in blowouts, but I also think stamina is a factor--my player Emerson has 2 stamina and is the only one of my trainees who really gets subbed out of blowouts. I think the GE might be trying to give him a couple minutes' breather when the game is already decided. What's your trainee's stamina?
