They were.
From what I heard on the radio, Riverdale could have sat on the ball for the win but they ran a play and fumbled and McCallie drove and tied. Riverdale throws the pick instead of sitting for OT and they you are.
I'm not sure about the clock when Riverdale fumbled midfield but the guys on the radio said they could've ran the clock. Riverdale had just recovered McCallies onside.
