Was an RPO and they were depending on Bosa to bite. If he plays it straight, KC is in trouble because #15 had nowhere to go.
It wasn’t a traditional RPO that the decison was based on the edge. The RB went the other way. I don’t think handing off was ever an option. So it’s not like Mahomes pulled it because of that.
I think it was an straight option for Mahomes. If Bosa played it straight, Kelce likely engages him. Then he could run or throw to another guy. Since Bosa bit, Kelce was free both as a downfield blocker and a target. It was a great design.
To your point, Bosa could have gotten them in trouble, but he would have had to get around Kelce too.
