Reports that the Philadelphia Eagles are about to sign Tim Tebow raise a host of questions. How will Tebow fare after two years away from the game? What role does Coach Chip Kelly have in mind for him? Will he be embraced by the tough Philly fans?

It is one thing to stockpile receivers or defensive backs. But teams can use only one quarterback at a time, and sometimes having even two candidates for starter can lead to a controversy that eats up a team.
