What went right: If this was Johnny Manziel's last game, he went out a big winner with 455 total yards and five touchdowns. Reliable Travis Labhart (seven catches for 76 yards, three TDs) and unsung Derel Walker (six catches, 113 yards, one TD) had clutch senior performances.
What went wrong: A couple of 15-yard penalties on senior wide receiver Mike Evans helped get A&M off to a slow start. A&M was only 2 of 6 on third downs in the first half, helping Duke take its 21-point lead.
Bottom line: A&M's offense was unstoppable in the second half, scoring touchdowns on five straight possessions as Manziel went 12-of-13 passing for 183 yards and two TDs.
What went right: With the game on the line, nickelback Toney Hurd Jr. and linebacker Nate Askew, a pair of often overlooked seniors, ended their careers with interceptions.
What went wrong: The entire first half. A&M was just awful as Duke averaged 10.1 yards per play.
Bottom line: The fourth-down stop on Duke's opening possession of the second half set the tone for the turnaround. And you can't overlook the stop by freshman end Daeshon Hall on Duke running back Shaquille Powell from the 1 to force Duke to settle for a field goal.
SPECIAL TEAMS: F
What went right: Trey Williams had a 33-yard kickoff return.
What went wrong: Duke scored 10 points off the kicking game with a blocked punt leading to a touchdown and adding a field goal after recovering an onside kick.
Bottom line: It's remarkable that A&M was able to overcome getting outscored 10-0 in the kicking game.
What went right: Defensive coordinator Mark Snyder switched his personnel for the second half to put some pressure on Duke; the change led to a pair of game-changing turnovers. New offensive play-caller Jake Spavital made good use of tight end Cam Clear, who had two catches for 38 yards after only two catches for 4 yards in the regular season. A&M also got 18 yards on three flip passes to speedy LaQuivionte Gonzalez as Spavital turned to the Aggies' version of the jet sweep.
What went wrong: A&M didn't look ready to play in the opening half, especially on defense. Duke started fast, and A&M is lucky it didn't trail 42-17 at the half.
Bottom line: A&M had 541 yards of offense and no turnovers in Spavital's play-calling debut.
What went right: The comeback, spurred by the seniors and Manziel, saved what was going to be a long offseason if A&M ended 8-5 coming off a two- or three-touchdown loss to Duke.
What went wrong: Evans (four catches, 72 yards) did have a game to remember if he opts to declare for the NFL draft with fellow redshirt sophomore Manziel.
Bottom line: A&M's offense played three quarters and the defense played about a quarter and half, but that and grit was enough to end a frustrating season on a huge positive.
