Actually this is a cool idea.
I would expand it a little more to include practice scrimmage games each day during "training camp" or before your first game, whatever you wish to call that period of time.
I also play a game called Eastside Hockey Manager. That game has daily scrimmage games during camp. You can't coach the games, but you can set who plays on each team, and view the stats.
It gives you more data to decide who should stay with the NHL team and who needs to be sent back to the AHL for now.
