If you want to see scores that are intentionally run up just go to the records section of the HSL and you will see them in the mid 20's and higher.
I am sure that B.C. held back to keep it to 4 at the half. I am sure at some point, probably the half, they put in their subs with the least experience. Tough to tell those guys not to score.
These are not classless coaches, or a classless program. I am sure they did what they could. Sportsmanship is high on their adgenda.
By the way, if you go the the HSL site referenced above you will see the Vikings you mention above have 2 of the top five score differential records. This by no means is directed at Coach Clark(I know he wasn't their at the time) or the current Viking team.
