NASHVILLE — On the biggest night of his life, so far, Kyler Murray wore a pink three-piece suit as a hat tip to his favorite movie, "The Great Gatsby", and bright white, designer sneakers as a nod to his favorite shoe company and sponsor, Nike.

The outfit became complete in Murray’s eyes when he donned a Cardinals hat after the team selected the former Oklahoma quarterback with the first overall pick Thursday night.

Arizona is where he wanted to go, so to Murray the evening was perfect.

For the Cardinals it was anything but. They will say different, of course, but drafting Murray is a move fraught with risk, and a mistake.

The Cardinals already have a young, talented quarterback, Josh Rosen, who was the 10th overall a year ago. They gave up two draft picks in a trade to get him.

A year later, they have more needs than Nashville has boots, and the only way Murray helps them is if he is a transcendent player.

I’m not convinced he will be. The Cardinals would have been better off sticking with Rosen and drafting Ohio State pass rusher Nick Bosa or Alabama tackle Quinnen Williams.

Cardinals team President Michael Bidwill, General Manager Steve Keim and coach Kliff Kingsbury think differently.

Drafting Murray creates more questions for a franchise full of them.

Will they keep both young quarterbacks? Trade Rosen?

If they were going trade Rosen, it would have been better to do it before the draft than after. But maybe the Cardinals didn’t get a suitable offer and are hoping one arrives before the start of the 2019 season.

Parting with Rosen comes at a cost. A year ago, the Cardinals added three quarterbacks: Sam Bradford, Mike Glennon and Rosen. Bradford and Glennon are gone now but occupy $8 million of cap space. If the Cardinals trade Rosen, that number escalates to $16 million for three quarterbacks who aren’t on the roster.

Or, maybe the Cardinals are prepared to start the upcoming season in an uncomfortable situation: with two young, talented quarterbacks taken only a year apart.

It’s the most affordable option. But that’s like a divorced couple staying under the same roof: it only makes sense from a financial standpoint.

It doesn’t sound as if Murray knows exactly what the Cardinals plan is.

“All I can do is go in, work hard and try to make the team better each and every day,” he said.

Rosen, who worked hard and tried to make the team better by attending all voluntary work this spring, including a minicamp practice on Thursday, can’t be pleased.

But that’s the nature of the NFL, where the philosophy is to love the one you’re with until something better comes along.

Rosen is working under a contract that guarantees him $17 million, and he’ll likely move on to a better situation.

Draft experts have long predicted Murray would be the first overall pick, and he underwent the expected scrutiny in recent weeks. There were questions about his commitment to football, how much control his father would have in his career and how Murray, who is on the quieter side, would handle media attention.

Thursday night, he did it with a smile. In a press conference after his selection, Murray mentioned that a Cardinals fan in the crowd waved at him to get his attention, then told him the Cardinals didn’t want him; they wanted Bosa.

“It was kind of funny,” Murray said.

The fan has a point. The Cardinals already have a quarterback and are in need of offensive linemen, receivers, tight ends, defensive linemen, cornerbacks, etc.

Murray, the Heisman Trophy winner last year, is immensely talented, and the first person to be taken in the first rounds of the NFL and Major League Baseball drafts.

But he is hardly a sure thing at the NFL level. He’s short (5-feet-10-inches) and started one complete season in college. It was only after that season that he committed to football over baseball, returning signing bonus money to the A’s.

Murray’s commitment to football could be tested by injuries and difficult seasons. Since entering high school, Murray’s teams have lost just three times when he’s started. The Cardinals lost that much in the first month last season, and it’s questionable if they will be any better this fall.

The Cardinals have been bold with their two biggest moves this off-season, but it’s questionable if they have been smart. Kingsbury was fired by Texas Tech after the season, has never coached in the NFL and couldn’t win in college with Patrick Mahomes as his quarterback.

Murray is short, and until January, regarded as more of a baseball prospect than a football one.

Supposedly, he and Kingsbury put the Cardinals among the cool, trendy teams leading the NFL into a different era.

I’m dubious. Like "The Great Gatsby", I don’t see this ending well.
