What it means: The Dolphins blew a 10-point lead with about five minutes left in the game and lost to the feeblest road team of the past three years. The Dolphins finished the season 1-7 at home, tying the worst record in franchise history.
Home finale: Such a humiliating defeat to punctuate such a humiliating home schedule might mean the end for head coach Tony Sparano. Dolphins owner Stephen Ross predicted his team would reach the Super Bowl this year, indicating where his head was after offseason acquisitions such as receiver Brandon Marshall and inside linebacker Karlos Dansby. ... Running backs Ricky Williams and Ronnie Brown might have walked off the field for the last time as Dolphins. Williams rushed 14 times for a game-high 71 yards. Brown had 12 carries for 37 yards and a touchdown.
Davone intervention: The football gods giveth, and they taketh away. With 31 seconds left in the first half, Dolphins receiver Davone Bess caught a touchdown pass that went through the hands of Lions defensive back Tye Hill. But earlier in the game, Bess fumbled on a punt return that set up a Lions field goal, and with a little more than two minutes left in a tie game, Bess fell down on a route, allowing Lions linebacker DeAndre Levy to intercept Chad Henne and return it 30 yards for the winning score.
Offensive implosion: The Dolphins amassed 425 yards and held the ball for nearly 15 minutes more than the Lions. Henne had a decent game until crunch time. The Dolphins led by 10 points with about five minutes left, but Henne threw his only two interceptions on third down in Dolphins territory inside the final four minutes. The first allowed the Lions to kick a game-tying field goal. The second left Sparano shaking his head.
Fins firsts: Popular fullback Lousaka Polite, who is virtually automatic in converting short-yardage third downs, finally scored his first NFL rushing touchdown in his seventh season. Mickey Shuler Jr., son of the former New York Jets tight end, caught his first NFL pass, a 28-yarder to set up a field goal.
What's next: The Dolphins will have the chance to punctuate their disappointing campaign with a victory against the New England Patriots in Gillette Stadium.
