Four things happened there that you don't want to see, as an X fan:
1) #3 was caught from behind, in the open field-- that happened twice on long runs-- but kudos to those Elder players for not giving up on both of those plays; (by the way, I thought #3 got tackled at the ~2- or 3-yard line-- but the refs spotted the ball at the ~5-yard line-- one of several very questionable spots during the game)
2) X gets to 3rd and 1 at the goal line, and runs a Wildcat formation with the smaller RB (#44) instead of the bigger back (#3 or #4)-- seems like a poor decision, in hind sight.
3) Now, it's fourth and 1 at the half-yard line, and X decides to go for the TD, with the bigger back (#3) in the Wildcat formation, rather than kicking the FG to go up by 7-- but (as has happened all too often this season), the offense commits a false start penalty before the play-- we'll never know for sure, but I think X would have converted that 4th and a half-yard with the bigger RB in the game, had they been able to execute on offense... do that, and the game is essentially over.
4) X misses the (essentially PAT-length) FG on 4th and 6 from the 6-yard line; (somehow, that FG was missed, but a 41-yarder to tie the game with 2 seconds left was made)
