I will respectfully disagree. I don't see any HS team beating a D3 college team. Maybe - and I say maybe - if you took a state championship team from TX, FL, GA or CA, they might be able to give a D3 team a game. but you're still talking about 17-year old kids facing players who are older, more mature, and have benefitted from several years in a college strength and conditioning program.
now, this year's version is not one of St. John's better teams, but they still have a QB who is among the top D3 passers in the country. their defense is the issue.
