The NFL's preseason is somewhat meaningless. Teams get as much out of holding joint practices as they do from meaningless games. But for Indianapolis Colts rookie quarterback Riley Leonard, preseason Week 3 against the Cincinnati Bengals was going to matter.
Indy didn't play newly-named starting quarterback Daniel Jones or backup Anthony Richardson. Most of the Colts' starters weren't going to play either. There is no need to risk presumed key players to injury when the real games begin in two weeks.
Leonard had the potential to show a lot, however. Even NFL backups are better than the players the quarterback would have faced in college.
