I'll go with SJJ. Barberton's only wins were against 2-4 Wadsworth and 1-6 Lakewood. However, their losses were to some pretty good teams. SJJ's QB Lichtenberg is a legit D1 player who had started since his freshman year. He led them to 2 4th quarter comeback wins (Findlay and Fremont Ross).
The key will be SJJ's defense. They couldn't stop Fremont Ross and were down by double digits. Can they stop a good offense? They couldn't stop Central Catholic or Fremont Ross. If SJJ's defense can play well enough, St. John's will win. Lichtenberg will get his scores, no matter who he plays.
Also, I have to say Tsiros (sp?) is a legit player as well. A great combo indeed.
But I wonder if Lichtenberg's great play is covering up for some weaknesses in St. John's. Reminds me of Riley Keller at Whitmer. Great QB masked a lot of deficiencies.
