Minnesota Vikings wide receiver Justin Jefferson turned a lot of heads on Sunday amid a rough day for quarterback J.J. McCarthy. The Vikings hosted the Chicago Bears at U.S. Bank Stadium, hoping to win the regular-season matchup against Chicago after they won the season opener with an 11-point comeback fueled by McCarthy.However, the story was completely different on Sunday. The Vikings didn't have any rhythm and only scored 17 points (14 in the fourth quarter). The broadcast showed Jefferson visibly frustrated, slamming his helmet on a table on the sideline.J.J. McCarthy played his fifth NFL game in Week 11. Many were unhappy about his performance, as he went only 16 of 32 for 150 yards and one touchdown against two interceptions.After a promising start to the season, the quarterback's level has decreased, and many think he wasn't ready to carry the burden that comes with a roster like the Vikings'.Justin Jefferson had a discreet game, too, which could also explain his reaction. He was targeted nine times and caught five passes for 61 yards. None of them translated into touchdowns, as Jordan Addison was the only wide receiver who found the end zone on Sunday.The Vikings tried to pull off a fourth-quarter comeback, but the Bears edged them out with a win that improved them to 7-3 and took them to the top of the NFC North standings.J.J. McCarthy sends message to Justin Jefferson, Vikings teammates after loss to BearsAfter the game was over, J.J. McCarthy was asked about how he processes the adversity after being successful in college. The former Michigan Wolverines star said this was an opportunity to improve and become more united."I think adversity is one of the greatest things for individual growth, collective growth, whatever it is," McCarthy said. "I think it really can separate teams or bring them tighter together. I feel like this team's been brought tighter and tighter together each and every week."We're just sick of losing, we need wins every single week and we're just gonna do everything we can to make sure we get those, but adversity is inevitable in this league, I understood that coming into it and it's just about how you respond."J.J. McCarthy, Justin Jefferson and Co. will return to the field on Sunday against the Green Bay Packers in another important divisional matchup.
