Rheams blew through the line in punt formation to deliver a touchdown for the Oilers with a dynamic special teams sequence.
On the first play of the second quarter, Rheams blocked the kick from Walsh punter Trey Crockett and brought it back 22 yards for the score.
It was a big play in a 14-point quarter after the Findlay offense had worked to earn a 7-0 lead after the first 15 minutes of regulation.
