Denver: It was a wipeout all right, just not the one expected by just about everyone outside the New York Giants.

“I don’t think anyone picked us to win this game,” Eli Manning said after the Giants’ first victory Sunday night, a 23-10 romp of the Denver Broncos in a prime-time stunner.

Manning called it “a special win” for a reeling team that was without six starters a week after losing three wide receivers to season-ending injuries, including star Odell Beckham Jr.

Capping a stormy week of injuries and infighting, the Giants (1-5) pulled off one of the season’s biggest upsets by dominating Denver in every phase from start to finish.

The Broncos (3-2), who are averaging just 14 points since their 42-17 rout of Dallas a month ago, blew a golden opportunity to close in on Kansas City in the AFC West.
