I can't help but think sometimes that it may make sense to find a way to put your backup QB into a real game so that his only experience isn't preseason. It's tough because, obviously, your starter gives you the best chance to win. You therefore generally put him in if you're blowing out the other team and your backup can play during mopup duty. The other case is if you're getting blown out and the game is unwinnable. The problem with that is it projects a lack of confidence in your starter. It makes me wonder if it would be possible to go against conventional wisdom and let him play just one series when you just have a decent lead. Of course, if that blew up in your face, the coach would never hear the end of it.
