The QB situation at Nebraska seems to be in line with what we see nationally. Most football positions see a rotation to some degree, but outside of injuries or blowout victories, backup quarterbacks almost never see the field. I can easily understand why it fuels a desire to transfer. To Matty's point, it's not shocking, but seeing the statistics is certainly interesting.
I maintain that we should be playing more than one QB so we are not finding ourselves in the messes we've suffered through when dealing with injuries (major or minor) to our starter. This year was a glaring example of the problem this presents but certainly we've had similar situations in many recent seasons. The 'starter' rarely makes it through a season unscathed and his backup must be ready to go on a moments notice.
I would submit that we won't see so many transfers if there is more than one QB with a legit chance of significant playing time and the opportunity to demonstrate why he may be the better 'starter'. It is quite common for players (it sure used to be anyway) to be listed as 'co-number 1s' on depth charts and to get plenty of snaps in either situational or 'platooning' cases at most other postions. The QB is the single most important player on the team, according to most commentators, and it seems just ludicrous that far too often teams go from being very good to mediocre if the starting QB goes down with injury or whatever.
Give the players a reasonable opportunity to compete and live game snaps are a key part of it. You can't make a truly fair and final decision based solely on practice, unless the seperation between two players is wide. In such cases, you immediately find another 'backup' to provide the needed depth and competition. IMO
