The Jacksonville Jaguars suffered a disappointing start to their season, losing 20-17 to the Miami Dolphins after leading 17-7 at halftime. Star quarterback Trevor Lawrence expressed disbelief at the team's second-half performance, completing only 12 of 21 passes for 162 yards with a touchdown, but struggled significantly in the second half, where he was just 3 for 7 for 37 yards. Critical turnovers, including a fumble by running back Travis Etienne, shifted momentum when the Dolphins capitalized with an 80-yard touchdown pass to Tyreek Hill. Jaguars coach Doug Pederson emphasized the team's lack of execution, particularly on third downs, where they failed on all five attempts. Despite the setback, Lawrence remains optimistic about the team's potential moving forward, highlighting their promising first-half performance and need to handle adversity better. The Jaguars will look to regroup in their upcoming game against the Cleveland Browns.
