Score is final and it doesn't matter, but here's what I see in the sideline video clip...

It was man to man coverage.
ND #20 was held by FSU #8 after #8 jammed him off the line.
ND #7 was jammed by FSU #3, who initiated the contact and then clearly made a move
INSIDE away from the play. The penalty was called on ND #7.
It looks to me like the job of those 2 FSU DBs was to jam the ND WRs and prevent them from running slants inside. Neither of them were assigned to or cared about #88 who went outside and caught the TD.
The DB covering ND #88 was FSU safety #26 and he was nowhere close to ND #88 because (a) ND #88 lined up deeper and ran a route outside, and (b) the traffic created by the FSU DBs jamming ND #20 and ND #7.
Winston played great in the 2nd half and ND certainly had other opportunities that they didn't capitalize on, but I think that game changing-call was a bad one. None of those 3 FSU defenders would have defended that pass. They guessed wrong and played inside when the play went outside.
One can only speculate, but if the roles were reversed, I don't think ND gets that call from an ACC ref on FSU's home field.
The good news is that ND proved a lot of people (and sports bettors) wrong last night and won over some poll voters (they only fell 3 spots to #8 in the Coaches poll). This should not be a surprise, as Brian Kelly's recruiting has been excellent since his arrival at ND. This is a more athletic, faster, and deeper ND team than the one that took the field against Alabama. After that National Championship game, Brain Kelly admitted ND had a lot of work to do to close the gap, and he has made very good progress. Vol fans may experience the same if Butch Jones is able to continue signing good classes and building quality depth. With road games left against #14 Arizona State and #21 USC, and a home game against Louisville, ND is still in the hunt for a playoff spot if they can find a way to win out and a few teams in the Top 7 take a loss, which they will.
