With Jason seriously injured, Matt must step up and become the team's first-string quarterback.

The Panthers suffer a humiliating loss. Lyla tries to help Jason believe that he will walk again.

Coach Taylor deals with outside influences on who to start at quarterback, with the biggest game of the year coming up against their rivals, who have taken it upon themselves to raise the bar by trashing the Panthers' locker room. His wife has no picnic, either, as she is given two days to plan a team tradition barbecue and the visiting list keeps getting bigger. Jason is moved to a rehab unit, still not accepting his situation, as his replacement and Matt, deals with competition when a new quarterback is brought in from Louisiana as a refugee from Hurricane Katrina.

While only two days away from their next game, Coach Taylor still doesn't know who to start at quarterback, and Jason still doesn't know that his best friend is spending a lot of time with his girlfriend.

With a very intimidating opponent on the horizon, Coach Taylor deals with his former starting quarterback and his unfaithful girlfriend and his new starting quarterback dating his own daughter. Lyla and Tim face repercussions of their own actions, and Smash deals with having to go back to his old hometown for the big game and dealing with old feelings regarding his father, all the while facing the issues surrounding his secret steroid use, especially when his sister begins to notice the changes in him.

While everyone is focused on the cheerleaders, who have an upcoming competition, they focus on giving Lyla a hard time. Smash begins to show signs of steroid abuse, and Coach Taylor finds another way to occupy his starting quarterback in an effort to squash Matt's efforts with the coach's daughter.

The Panthers are preparing yet again for another game they can't afford to lose. Jason (Scott Porter) still finds it difficult to adjust to life at home, and the feelings he still has for Lyla (Minka Kelly) don't make it any easier. Meanwhile, at what couldn't seem like a better time, Matt's (Zach Gilford) dad comes home from Iraq, but the homecoming is not what Matt expected. To make situations even more complicated, UT has taken an interest in Coach Taylor, whose popularity continues to grow, and Smash becomes more and more dependent on unnatural substances to keep up with the competition.

When an assistant coach is quoted in the media with racial intentions, he draws a line between the team, right at playoff time. Julie and Tyra are forced to join the powderpuff game as a result for skipping class, and Julie's dad is a bit elated when she's picked for quarterback by Matt.

Upon returning to the Panthers, Coach Taylor finds himself trying to mend broken fences between his quarterback and his halfback and attempts to find a little intimate time with his wife. Tim recruits Lila in trying to talk Jason out of the risky surgery he has scheduled in Mexico, while Landry's father tries to put up a fence between his son and Tyra.

The coach's wife enlists the aid of Tyra and Lila to secure entertainment for the annual Pantherama event, while the coach enlists the aid of Buddy, who found a hot new football player for him, but the new prospective star has a family that's run out on him, and Tami won't let him play football until that scenario is amended. Julie enlists the aid of journalism in an effort to help her get over the loss of Matt. Smash doesn't want help from anybody, while he turns his back on the possibility of a great education, opting out, instead for a chance at more recognition from the pro ranks while playing for a more-notable school.

Santiago feels the pressure about the upcoming football game, while pressure mounts between Julie and her mother surrounding the christening of the new baby in the family. Tim feels the pressure of his new roommate, while Jason does his best in getting back into the dating world.

The coach's need for his own space in his own house doesn't just stop at throwing out Tim, even though his wife has her own needs when it comes to caring for her family and Smash's need for choosing a college is taking its toll on his family, especially his mother.

Tami doesn't want to break the bond with her infant daughter by leaving her at daycare. And as Santiago's former friends show up at his house to retrieve their bond, Buddy feels the bond with his material possessions, while his daughter, Lyla, takes a job at a Christian radio station.

The hardships in Saracen's life begin to get to him, and he and Riggins, who is still pining away for Lyla, commiserate; Julie feels left out when it seems like her mom is more focused on the volleyball team than on her; Smash's suspension hurts the rest of the team's morale, and it has an unexpected consequence for him; Tyra becomes jealous of Landry's new girlfriend.

However, Brian is very shocked when the most unlikely place offers him what may be the opportunity of his life.

A few days proves to be too long as Coach Taylor begins to feel a bit jealous. Elsewhere, Jason Street hears the biggest news of his life since his accident and must decide if he is willing to change his life completely. Meanwhile, Tim Riggins continues his pursuit of Lyla by getting his own radio show at the Christian radio station.

The press grills Coach Taylor about the upcoming season while the teachers grill his wife, the new principal, about the budget and the necessary cutbacks, while Buddy and the football team have the best of everything. A new quarterback enters the picture and Matt feels threatened and Riggins is still up to his old game plan about not feeling anything. Tyra's new guidance counselor lays some rather bleak news on her, causing her to walk out of school, only to find some personal resolve within herself to attempt to rectify her situation.

When Coach Taylor realizes that it's not Smash's knee that's holding him back, he comes up with a rather unique way of laying it all on the line. The doctor lays it all on the line for Matt, who, legally, can't take care of grandmother, anymore, while Buddy goes out of his way, laying it on the line for Tami over the jumbo tron issue, and laying it on the line with Tim, who's now dating his daughter. Meanwhile, Tyra realizes that it's easier to lay it all on the line by taking shortcuts in winning the student body presidency.

Coach Taylor feels pressured when the boosters corner him at the annual barbecue. Tim gets pressured from his brother about helping him score some extra cash to pay for his impending wedding, while getting pressured at the same time, from Lyla, to try and turn his life around...and her father isn't any help, either.

McCoy feel more comfortable with the team. Matt's comfort level with his new position on the bench is felt by everyone close to him, including Julie as they continue to grow closer together.

Buddy tries to use Tim to get to Lyla, who's still mad about losing her college fund to a business deal and it gets worse when she finds she's been accepted by the college she's always dreamed of.

Meanwhile, the issue over splitting Dillon High School seems small, compared to the fact that outside influences such as money and a control for power continue to affect Coach Taylor, even while his contract comes up for negotiations.

Coach Taylor is faced with building a football program from the ground up after the redistricting splits Dillon into two high-school districts. East Dillon is without funds, without a qualified coaching staff and without talent after the gerrymandering that was done by the Dillon Panther Boosters.
