In a regular season with four stinging losses defined by the theme what if?, here are the most heartbreaking plays of Tennessee’s 2015 season in chronological order:

1. Tennessee 24 Oklahoma 17.  Sooners’ ball, fourth-and-goal at Tennessee’s 1-yard line, first overtime: Oklahoma QB Baker Mayfield kept the football and ran it in for the game-tying touchdown. Mayfield was particularly gutsy in the fourth quarter and in overtime, but this play was a game-saver for the Sooners. If Tennessee’s defense had tackled Mayfield short of the goal line, the Volunteers would have survived Oklahoma’s ferocious comeback. Instead, Mayfield used RB Samaje Perine’s extra block on the edge to sneak his way into the end zone and force a second overtime.

2. Oklahoma 31, Tennessee 24.  Vols’ ball, third-and-12 at Oklahoma’s 27 yard line, second overtime: Dobbs set his feet and fired the football down the field, but Oklahoma’s Zach Sanchez stepped in front of the intended receiver and came up with the game-winning interception. Dobbs had TE Ethan Wolf open underneath, but was focused on getting the first down on one play instead of settling for a fourth-down attempt.

3. Tennessee 27, Florida 21.  Gators’ ball, fourth-and-14 at Florida’s 37-yard line, 1:26 remaining in the fourth quarter: It was by far the most agonizing play of Tennessee’s season. Tennessee decided not to blitz Florida QB Will Grier, and Grier had plenty of time to stand in the pocket and find an open receiver. Sure enough, Grier completed a pass to WR Antonio Callaway beyond the first-down marker. Tennessee CB Malik Foreman took a poor tackling angle toward Callaway, who turned upfield and sprinted down the sideline for a 63-yard TD.

4. Florida 28, Tennessee 27. Vols’ ball at the Florida 38-yard-line, 3 seconds left in the fourth quarter: Aaron Medley came in for a 55-yard field-goal attempt to win the game. If Medley made the kick, Tennessee would have won. But he didn’t. The kick was long enough, but a few inches wide of the right upright. Tennessee was only inches away from playing in the 2015 SEC championship game.

5. Alabama 19, Tennessee 14. Vols’ ball, second-and-24 at Tennessee’s 21, 1:18 left in the fourth quarter:  It was going to be a huge challenge to drive the ball 79 yards down the field against Alabama’s staunch defense, but Tennessee’s slim comeback hopes died when Alabama LB Ryan Anderson sacked Dobbs and forced a fumble. Alabama recovered and went on to win the game.
