Really, there were three "fluke" plays that made a huge difference.
1. First TT touchdown drive, 3rd and 13 from the Tech 27, pass coverage is good, ball is tipped by defender, but the Tech receiver makes a brilliant grab as he's going down. 1st down instead of Tech being forced to punt. That would have ended the TD drive right there. 7 point swing.
2. Dropped lateral pass with Tech return for TD, one of the all-time worst Husker plays. Another 7 points.
3. Gilleylen drops a sure TD pass that was right in his hands. Another 7 points.
Those three plays basically led to 21 points, the difference in the game (although clearly Tech made other plays on that first drive, it would have ended without that 3rd down conversion).
Not to mention the first and goal for Nebraska that was killed by stupid penalties, leading to no score.
Tech made the plays, Nebraska did not, but the three plays above could have easily gone the opposite way from what they did and that was the difference in the game. Yes, the offense has serious problems, but this game turned on just a few plays.
