Read this article and answer this question The Panthers came into the Monday night game as one of four undefeated teams in the NFL, while playing their second game in eight days. The team took to the field amid fireworks, as is their custom for prime-time contests. A heavy rain kept up most of the night, which saw both the drenched crowd of over 74,000 stay in their seats and a 23-6 Panther lead dissolve by a 17-point Colts comeback in the 4th. Indianapolis sent the game into overtime with a field goal following a near-pick by Kuechly; the extra period began close to midnight. Each team managed a field goal on their first two possessions. Carolina got a break when Colts QB Andrew Luck threw his third interception, which was picked off by Kuechly on the game's 154th play, according to ESPN play-by-play man Mike Tirico. A few plays later, Panthers kicker Graham Gano hit a 52-yard field goal, his longest of the season, to give Carolina the win early Tuesday morning. With the win, the Panthers went 7-0 for the first time in franchise history. Also, Carolina became the last undefeated team in the NFC with the Packers' loss to the Broncos the previous night on Sunday Night Football.
