After months of speculation the team was going to draft fellow quarterback Kyler Murray with the first overall pick, head coach Kliff Kingsbury reportedly confirmed it to Rosen only one minute before the pick was made.
"Hey, so we're about to draft Kyler," Kingsbury reportedly told Rosen on the phone. "...I don't really know what happens now."
What happened next was the Dolphins sent a second-round pick and a 2020 fifth-round pick for Rosen, ending his time in Arizona after just one season.
It also ended a stretch of mixed messages from the first-year head coach, who was praising the quarterback right up until the draft.
"I think Josh has done everything humanly possible to show what type of quarterback he is, what type of competitor he is," Kingsbury said at minicamp two days before selecting Murray, per Bob McManaman of the Arizona Republic. "I’ve said it all along, I couldn’t be more impressed with his approach. He’s a great player."
This helped contribute to the confusion felt by Rosen heading into the first round, holding out hope the Cardinals would select a player at a different position.
"My heart really didn’t believe it was going to happen until a couple minutes before it happened," he said after the draft, per Robert Klemko of the MMQB.
While this whole situation was seemingly handled poorly, Rosen gets a new chance to show what he can do with the Dolphins in 2019.
