The problem was that they started playing as if the game was in hand,while Andrew Luck and the playofftested Colts started to play as though they had nothing to lose.The result was a furious secondhalf rally,one made possible by unconscionable breakdowns by a defense that was spectacular during a 90 start.Luck torched a secondary that wilted when it faced premier quarterbacks such as Peyton Manning and Philip Rivers,and his 64yard touchdown pass to T.Y.Hilton with 4:21 left finished off the secondbiggest comeback in NFL playoff history.I sat there and talked to them this morning and there were a lot of long faces,Chiefs coach Andy Reid said Sunday.They had their hearts ripped out.I can work with that.They should hurt,Reid said.Thatll make us better.The last time the Chiefs won a playoff game,Joe Montana was the quarterback and the Titans were still the Oilers.Since then,there have been all manner of playoff heartbreaks:The Chiefs missed three field goals against Indianapolis after the 1995 season,when they had gone 133 during the regular season and harbored championship aspirations.Two years later,the Chiefs lost a 1410 heartbreaker to the Denver Broncos,who would go on to beat the Green Bay Packers and win the Super Bowl.After the 2003 season,the Chiefs lost again to the Colts in a game featuring two of the leagues premier offenses and in which nobody punted.But the way that Kansas City melted down Saturday may trump all of those disappointments.Its hard to put in words,to lose a game that we clearly had control over,said linebacker Derrick Johnson,who is now 03 in playoff games in his nineyear career.Coming from having the first pick last year to making the playoff this year,we did accomplish some things,Johnson said.At the same time,our standard is very high and this one hurts.
