They forced the best quarterback in the NFL to tie a career high with three rare interceptions and an all-time offense to commit four total turnovers.
They even took a 10-0 lead over the defending Super Bowl champions. And they narrowed a 20-point deficit down to six points with 4:15 remaining.
But the upstart Dolphins, thriving in the second season of the Brian Flores era, were unable to finish the job against the Kansas City Chiefs on Sunday.
Star and reigning Super Bowl MVP Patrick Mahomes led the Chiefs on a stretch of 30 unanswered points in their return to Hard Rock Stadium since winning Super Bowl 54 in February, and a game-deciding field goal drive that handed the Dolphins a 33-27 loss in front of an announced crowd of 13,057 people with respect to COVID-19 regulations on Sunday.
