You might be remembering the '13 season, where the review only affected the ejection. In '13 the penalty stood no matter what, even if replay determined that no targeting had occurred. In '14 it was changed so that if the replay determined that no targeting occurred, the 15 yard penalty was reversed as well. I don't remember one instance in any game I watched last year where the replay officials determined that another PF penalty occurred instead of targeting. It was either upheld or completely waived off.
After watching the game on the replay today and seeing the various angles, the officials upheld Laguda's ejection because of the contact with the facemask. His technique was perfect, head-up, led with the shoulder, however his target zone was too high. Ironically if he would have lowered his head and hit shoulder to chest with his head to the side (more dangerous technique) he would have avoided the penalty. Although I don't like the penalty, I can't say that they made the wrong call, had it not been called in the first place would have been best, but the rule says to error on the side of calling it a foul. The rule has had its intended effect, to reduce the number and violence of hits on defenseless players, and encourage more wrap-up tackling. It is a coachable moment.
