HS vs. College

[Nevadaref]

Rut made some excellent comments already, but I would like to add a thought.

It seems to me that the biggest difference between the HS and college officials is the amount of contact that triggers a whistle.
Mostly, the HS only officials let too much go, while those work college have had it drilled into them over the past few years that we need to clean up the game. That means control rough play and whistle contact that prevents freedom of movement.
Although the college players are bigger and stronger, I believe that the game is called more precisely because everything is captured on video and the officials are highly scrutinized. At the HS level, one can get away with much more because there isn't the same level of review.
