well, the other day, I had this reliever at the bullpen that I was planning to use, and by mistake took him off the bullpen and back to the bench, after he was already warmed up.
I thought that the game would reset his condition so that when I dragged his name back into the bullpen, he would be cold again. He wasn't, he was still warm. I thought it was a nice touch. He went on to save the game
On the other hand, I totally agree with the original poster's idea.
