Can you describe the plays on which those 2 interference calls were made? I assume you watched the game and are prepared to discuss their intentionality, and how the specific plays played out.

Receiver Involved

"DaVaris Daniels, WR: Daniels caught six balls for 107 yards and a touchdown, crossing the century mark for the second time this season. He proved difficult to defend 1-on-1 all day, drawing pass interference flags and teaming with TJ Jones to give Tommy Rees a strong tandem in tough passing conditions."

First Qtr

On previous drive, DaVaris Daniels made a fool of BYU's Rbt Daniel in being wide-open on a 61-yard bomb. In fact, Rbt Daniel got help from BYU safety Skye PoVey -- but didn't really "help".

So. NEXT time ND gets the ball...very first play, of course...ND is going back to D. Daniels. Rbt. Daniel, not wanting to get beat again is flagged for interference...lst play of drive that started @ 6:48 remaining ... penalty gave ND a first down @ ND 36...sideline route.

Here, you can see the penalty for yourself in a photo taken by a Chicago Trib photographer: Photos: Notre Dame 23, BYU 13 (scroll down to third pix from bottom)

(a) Robert Daniel is not looking @ the ball + is face-guarding with right arm in face of DaVaris Daniels; and
(b) Robert Daniel has initiated contact on the receiver with right elbow (& likely left hand -- unseen in photo)

BOTH (a) and (b) are grounds for interference ... face-guarding without looking @ the ball is flag-worthy.

2nd QTR

Pass interference by BYU's Rbt Daniel on ND's DaVaris Daniels...last couple minutes of half -- penalty gave ND first down @ BYU 27. Receiver was accelerating by defender...to left of middle of field (camera side) ... would have been a hold if ball hadn't already been in air.

Both calls were 1-on-1 coverage.

2nd QTR facemask by #11, Dallin Leavitt

This occurred on a tackle 7 plays later on same drive in BYU territory -- along the right sideline ND driving in ... the instant replay showed a grasp of the top inside of the helmet. You cannot grasp any part of the inside of the helmet...all such grasps are given the facemask signal -- whether the mask itself or only the inside of the helmet is grasped.

Funny stuff. Wasnt really looking for the play by play.

I guess my disconnect is as follows ... when I learned the game of football, if a defensive back was faced with a choice of a 15 yard penalty for interference or a huge play/touchdown, well it was wink wink nod nod, if you know what I mean. Don’t give up the score. We’ll get em on the next play. Try to make it look like legitimate defense if you can, but don’t give up the score.

Now if you want to call that a moral failing, well, OK. The BYU guys are, by your definition, moral failures.
