I have rarely seen a punt turn the momentum the way the Lufkin punt did in the fourth. KC up 21-14 and Lufkin punts the ball. It is downed on the 3 yard line. Two plays later the ball is fumbled. Lufkin ball at the four. TD.
Kickoff, KC has trouble with it. Stopped at the 15 and a holding penalty. Move the ball back to the 8. Run a play and another holding penalty. Ball now on the 4. Safety on the next play. Safety kickoff and Lufkin drives down and makes it 30 -21.
Lufkin kicks off and the ball rolls between the KC returners legs (5 hole if you watch hockey). They start from about the 4 and fumble on a pitch back and Lufkin recovers in the end zone.
Lufkin kickoff and KC doesn't do anything with it. Punt. Lufkin's second string comes in (and probably KC's as well. Back up QB runs an option and KC doesn't tackle him and he takes it 65 yards for a TD.
Lufkin looked awful for the first three quarters. Turnovers, unsportsmanlike penalties, personal fouls. KC kept Lane in complete check the entire game except one play in the first quarter. That punt just changed the momentum and KC couldn't recover. They never got beyond their own 12 yard line in the last quarter.
And the refs were WAY off of their game, but they sucked equally. One turnover against Lufkin and the back judge never moved. Offensive and defensive came out for the other team and the back judge was still standing in the same spot.

KC gets ready to run the ball and the back judge is standing 8 yards deeper in the backfield than the referee. Many other stupid little mistakes like that, but I am not sure that they determined the outcome. Others may disagree and that is what message boards are for.
BTW, the score does not even come close to telling how closely the game was contested. It was a battle between two quality teams and the breaks went Lufkin's way in the last 12 minutes.
One last thing, I have never watched an opposing bands halftime show that I enjoyed more than the KC performance. A salute to college fight songs ROCKED!
