I should get shot for saying this but I think it's really possible they would like to have Riley as the starter but they don't completely trust him yet. He reportedly had some issues throwing interceptions at the beginning of camp and that has been described as catastrophic. He has an abundance of confidence, the strongest arm, can make all the throws on the field, and is very mobile. Reportedly they all know the offense so I think he has the edge but in the beginning he dug himself into a hole. Last year Cincy lost 3 games, all by a TD or less. Against Toledo they threw 2 interceptions, against Louisville 3 interceptions, and against Rutgers 2 interceptions. I think Riley just has to prove he has learned to take care of the football and until he does I think Nate may have just that much of an edge on him. Jmo, grasping at straws really, but based on everything I've heard and read to this point, I'd probably go with Worley or Nate to start but my first choice would be Riley when and if I ever truly felt like I could trust him to take care of the football. He may be the most promising atm but he may also carry the most risk. JMO.
