I wouldn't, and mostly because the idea that a player's confidence or morale suddenly plummets just because he missed a tackle or let in a goal or whatever, is IMO silly to start with. These are pro athletes; they don't get discouraged and start to mope when things go wrong. If anything, the reverse is true; that's when a pro picks up his game. Regardless, what's next? Hit X to initiate pep talk or group hug?
I'm perfectly happy the current system where individual players' gameday form, energy, etc. is displayed before kickoff. I have no interest in anything more than that.
