Me, I just have one thing against this proposition, it's the fact to know right at the beginning. Unless the opponent coach tell you, it's impossible to guess his choice, IG or IRL. After 24 minutes it becomes possible. So I wouldn't mind if it is shown but during halftime.
i would prefer it them too, not because the realistic aspect but for the fun of guessing in the first minutes of the game. Did i have a lucky strech in the offense, or is the opponent defense off etc. And aftera while, i like to be sure but at least the first 5 min i prefer no to know.
