Kirk Cousins knows plenty about NFL history. The Vikings’ quarterback was only 4 when Buffalo came from 32 points down to win a game in the 1992 playoffs, but he has seen replays of the game on television. Until Saturday, the Bills’ 41-38 overtime win over the Houston Oilers was the biggest comeback in NFL history. Then the Vikings at U.S. Bank Stadium came from 33 points down to defeat the Indianapolis Colts 39-36 in overtime. “I’m a fan of football,’’ Cousins said. “Walking off the field, when somebody said it was the largest comeback, I thought of (Bills quarterback) Frank Reich (and Houston quarterback) Warren Moon. That game. I thought, ‘It couldn’t have been bigger than that comeback?”’ It was. The Vikings trailed 33-0 at halftime, and that was the score until Cousins hit K.J. Osborn with a 2-yard touchdown pass with 8:22 left to cut the deficit to 33-7. That got the comeback going. And Cousins, who completed 34 of 54 passes for a career-high 460 yards with four touchdowns and two interceptions, threw for all his TDs and for an amazing 417 yards after halftime. “Incredible game,’ Cousins said. “Great to win. Great to come back. … Something like that doesn’t’ happen to average people.” Cousins hardly was average on Saturday. The Vikings had little margin of error in the second half, and he helped bring them back. Cousins’ other touchdown passes were throws in the fourth quarter of 8 yards to Justin Jefferson, 1 yard to Adam Thielen and 64 yards to Dalvin Cook on a screen pass. After the throw to Cook with 2:15 left in regulation, Cousins threw a two-point conversion pass to T.J. Hockenson to tie the score 36-36. “You cannot win the football game the way we had to go win it without your quarterback playing at an incredibly high level,’’ said Vikings coach Kevin O’Connell. Cousins admitted that his “thoughts weren’t great at halftime.” Bu after he threw the touchdown pass to Jefferson with 12:53 left in regulation to cut the deficit to 36-21, he said he began to believe that the Vikings could win. “I was asking myself that, ‘At what point does it become a normal NFL football game?’’’ Cousins said. Off the top of my head here, when we cut it to 15 (then) this is right there.” Jefferson caught 12 passes for 123 yards, Osborn had 10 receptions for 157 yards and Cook caught four balls for 95 yards. Cook also ran for 95 yards. “With him being a leader, we had to get something going,’’ Jefferson said of Cousins. “He made some tough throws. He put us in great position.” After the game, Cousins showed up for his postgame interview wearing a loud purple jacket with Vikings logos on it. He did say he would have have put something else on had the Minnesota not lost. “My wife dresses me,’’ Cousins said. “She put it out last night. I looked at her like, ‘I don’t know. She nodded, ‘You go to do it.’ So here we are. Yeah, fun jacket.” And it certainly was a fun win for the Vikings. “Moments like this you want to enjoy,’’ he said.
