Second-half offensive slumps had a face at Arrowhead: Marquez Valdes-Scantling reaching for Patrick Mahomes’ pass as a possible winning touchdown slipped away. Late against Philadelphia on November 20, 2023, the Chiefs receiver had beaten cornerback Bradley Roby downfield. Mahomes gave him a chance. The ball glanced off his fingertips.
Kansas City had led 17–7 at halftime. Philadelphia won 21–17, leaving the Chiefs with thirty scoreless minutes and plenty to explain.
Blaming halftime adjustments offered an easy answer. It also struggled to explain the receiver running behind the coverage with the game still there to win.
That drop did not erase everything Philadelphia accomplished. Nor did it absolve Andy Reid of responsibility for an offense that stopped scoring. But it exposed the problem with treating an empty half as proof that one coordinator outsmarted another.
Was the play wrong? Did the quarterback miss something? Or had the offense found exactly what it wanted and failed to finish?
Those questions lead to different repairs. A halftime speech cannot catch that pass.
The work starts while the benches are still warm
After joint practices with Green Bay in August 2023, Bill Belichick described the job without dressing it up. “Figure out the problem, what it is. Identify it, make an analysis and then fix it.”
He also placed that work between plays and between series. Coaches do not need a locker-room door to close before they can correct a protection call.
Imagine a quarterback returning to the bench after a free rusher forces an incompletion. The center thinks the running back should have picked up the pressure. His back thinks the line slid toward it. Waiting until halftime would waste the next possession.
Second-half offensive slumps can grow from an argument the offense never settled in the second quarter. A useful correction might take one sentence: slide the line left and leave the back responsible for the edge. Getting everyone to hear, understand, and carry out that instruction matters more than filling a whiteboard.
The next series tests whether the message landed. If the same rusher comes free again, the staff has more work to do.
The first half might have been shakier than it looked
Two touchdown drives can make an offense look comfortable. Rewind them, and the picture might change. Suppose a receiver wins a contested ball on third-and-long. Another possession survives because the quarterback escapes a sack and scrambles past the marker.
Both plays deserve credit. Neither guarantees the offense can keep overcoming bad early downs.
On the sideline, the coordinator still has a problem. His first-down run keeps meeting a defender in the backfield. The quick pass keeps leaving the receiver short of the sticks. Eventually, someone misses the difficult catch that had kept those possessions alive.
Second-half offensive slumps can expose weaknesses that early highlights concealed. The offense may have spent the first half asking its best players to rescue possessions. Once those rescues stop, the box score looks as though something changed during the break.
Field position deserves the same scrutiny. A touchdown drive beginning at the opponent’s 30 asks far less than one beginning at the offense’s 10. Before praising the early plan or condemning the late one, count how much field each unit actually had to cover.
Playing with a lead can make an offense easier to defend
A coordinator protecting a lead faces a temptation: remove everything that could go wrong. Keep the tight end in to block. Give the running back another protection assignment. Trade a downfield route for one more body around the quarterback.
Sometimes that choice saves the possession. It can also leave only two receivers trying to separate from a secondary with plenty of help.
The quarterback gets extra protection but fewer places to throw. As he waits for someone to uncover, the pocket can still collapse.
This is what second-half offensive slumps can look like when caution changes the offense itself. The defense no longer has to account for a tight end releasing up the seam or a back threatening the flat. Those defenders can help squeeze the routes that remain.
A running clock still needs first downs
Consider a first-down run that gains one yard. Another handoff gains two. The offense burns time, then faces third-and-seven with a defense expecting a pass.
Calling a run did not automatically make the sequence sensible. The defense, the blocking matchups, and the remaining clock should determine whether that trade helps. A coordinator who keeps handing off into a crowded front may protect the football while making another punt increasingly likely.
Nor does aggression require a deep shot. A play-action throw into the flat can threaten a first down while giving the quarterback a quick decision. The question for the play caller is practical: which call gives these eleven players their best chance to keep the ball?
Kansas City needed more than a new call sheet
Against Philadelphia, the Chiefs committed two red-zone giveaways and seven penalties across the game. “Today, it was penalties and miscues,” Mahomes said afterward.
Those failures did not all happen after halftime. Kansas City already had mistakes to correct before its second-half shutout began.
The late drop showed one way a possession could fail. A fourth-quarter fumble by Travis Kelce showed another. Neither required Philadelphia to cover every receiver on every snap, and neither would disappear simply because Reid chose a different formation.
Second-half offensive slumps can contain several breakdowns that demand separate attention. Ball security requires attention to how a runner carries the football through contact. A protection mistake demands a clear assignment and the technique to execute it. An open receiver’s drop raises questions about finishing the catch.
Coaches own that preparation, too. Calling everything an execution problem can become an escape hatch for a staff.
The better question asks why the same players keep missing assignments or losing the same matchup. At some point, the plan must account for what they can reliably do.
That might mean helping a struggling tackle or giving a receiver a cleaner release. It also means recognizing when the call created a good opportunity and the player simply missed it.
Atlanta’s collapse did not begin at halftime
Julio Jones balanced near the sideline, secured Matt Ryan’s pass, and gave Atlanta a chance to finish Super Bowl LI. His 27-yard catch put the Falcons at New England’s 22 with 4:40 remaining. Atlanta led 28–20. A field goal could have forced the Patriots to find two scores.
Then Trey Flowers sacked Ryan for a 12-yard loss. A holding penalty later helped push the Falcons out of field-goal range. Atlanta punted, and New England eventually won 34–28 in overtime.
Jones had just made a spectacular catch. The offense needed to protect the scoring opportunity he created. Instead, lost yardage turned a promising possession into another chance for Tom Brady.
Second-half offensive slumps become harder to explain with a single locker-room story when the timeline refuses to cooperate. Earlier in that same half, Atlanta had driven 85 yards for a touchdown and a 28–3 lead. Whatever New England discussed during the break, it did not immediately shut down Ryan’s offense.
The decisive questions came later. How much risk should Atlanta accept within field-goal range? Could its protection hold up long enough for the pass to develop? What should Ryan do when the pocket started closing?
Those questions belonged to the possession unfolding in front of them. The halftime meeting had ended long before Flowers reached the quarterback.
The next snap tells the story
Atlanta lost ground after Jones put it within reach of points. Kansas City found an open receiver after spending nearly an entire half without scoring. Each offense needed something different from the players on the field.
Second-half offensive slumps demand attention to those differences. Watch the receiver’s route before looking toward the coach. Does he turn with room to work? Has the quarterback started his throwing motion, or does he hesitate until the defender closes?
Follow the sack backward, too. A holding penalty might have created the obvious passing down. An earlier pressure might have warned the coordinator that his tackle needed help.
Coaching deserves scrutiny at every step. The staff must recognize the problem, choose a workable answer, and prepare players to carry it out. Players still have to block, throw, and finish the catch.
A useful halftime conversation should leave evidence on the field: a clearer protection call, a quicker outlet, a better matchup. Judge those changes by the opportunities they create and the failures they prevent.
Late against Philadelphia, Mahomes found Valdes-Scantling beyond the coverage. With the scoreless half nearly complete, Kansas City still had a chance to win. The receiver reached, and the ball hit the ground.
The touchdown was there to catch.
