The Kansas City Chiefs defeated the San Francisco 49ers 31-20 in Super Bowl 54 Sunday. For the third time this postseason, KC came from behind to beat their opponent, thanks to some late-game magic by Super Bowl MVP QB Patrick Mahomes. For the second time in Kyle Shanhan's coaching career, his team fell apart in the fourth quarter of the SB. With Danny O'Neil's help, we juxtapose Mahomes ability to operate under pressure with Jimmy Garoppolo's timely collapse. Could the Niners be headed for a SB hangover, like the Rams experienced after their loss last year?
