guess I got it right during the presentation.
We in Mass have to get NCAA rules out of our heads.
I was at a party this past weekend that was attended by a Mass. official. He worked the wings (Aric Friend- if any might know) and we discussed calls that might occur more often from his position. Some such were :
(1) encroachment by B/R is a dead ball foul;
(2) pass doesn't have to be catchable, just in the area of receiver for DPI;
(3) forward fumbles going OOB given to OOB spot - can always have IFP in deemed intentional;
....at that point, our wives pulled us apart, as it was a party and not a football game
!!!
SUGGESTON : Focus on rule differences on the calls you'll be responsible for. The white hat will have the biggest challenge, as told several years ago, NCAA had +70 exceptions in Rule 10 (penalty enforcement) while NFHS had 16. The "all but one" principle covers many.
