Mighty Quinn?

Jay Cutler turned Brady Quinn’s big night into his own prime-time showcase. Cutler passed for a career-high 447 yards, throwing three touchdown passes in the fourth quarter Thursday night — the last an 11-yarder to Brandon Marshall with 1:14 remaining — to rally the broken Denver Broncos to a 34-30 win over the Cleveland Browns that spoiled Quinn’s highly hyped debut as an NFL starter.
