When Brandon Marshall looks at his right index finger, it provides a reminder. It is bent but points directly to one of the former linebacker’s favorite NFL memories. It came during the final plays against Kansas City on Sept. 17, 2015. The Broncos had tied the score with 36 seconds remaining, leaving them prepared for overtime. For all the importance of Peyton Manning stiff-arming Father Time, of receiver Demaryius Thomas’ eye-widening performance, it was Marshall who made this game memorable with a single punch. On first-and-10 from the 20-yard line, the Chiefs eschewed taking a knee as quarterback Alex Smith ran a draw play, handing off to Jamaal Charles.
