Advantages and disadvantages of playing two quarterbacks:
1. In theory, it gets two good players into the game. Some awfully good football players have stood idly by watching another quarterback.
2. Buys time. If you don't know which quarterback is best, let them settle it on the field.
3. Defensive stress. Preparing for two quarterbacks, if they're different styles, is a defensive coordinator's worst nightmare.
1. Team chemistry. Hard to get behind two team leaders.
2. Offensive rhythm. Changing quarterbacks in the middle of the game can lead to some stuttering possessions.
3. Admission of deficiency. The old adage is that if you've got two quarterbacks, you really have none. If no one wins the job, that's not a good thing.
