So you're looking for a team that just randomly shuffled in different QBs regardless of the situation and was successful? No, that has not happened.
I'm looking for examples of teams that had two really good QBs, and both QBs played a lot of minutes. Seems a lot of people are convinced that Waters will start but that Sams will be in the game quite a bit as a QB, WR, RB, etc.) I'd love to see it. From everything I've seen/heard, Sams is as good an athlete as we have on this team. But, for whatever reason, this scenario doesn't tend to play out much in college football. the backup is the backup except for a handful of situational plays or in mop-up duty.
This is how I predict Sams is used. For one reason, Snyder probably doesn't want to risk injuring his backup QB, considering our starters tend to get dinged up fairly regularly.
