ESPN NFL Draft expert Mel Kiper Jr. had Nick Bosa going to the Arizona Cardinals at pick No. 1 in his most recent mock draft.

However, after Kyler Murray weighed in at the combine and was bigger than people initially thought, Kiper has changed his mind.

Here's what Kiper had to say about Murray after the combine:

I’m going to probably put him No. 1. I think the Arizona Cardinals have kind of a dilemma. Do they feel that Kyler Murray is a significant upgrade over Josh Rosen? Then you have to trade Josh Rosen, and do you have an interested party there in maybe the Washington Redskins or the Miami Dolphins. Somebody like that, you get that first-round pick from a team for Rosen.

I think Kyler Murray fits Kliff Kingsbury’s offense. Josh Rosen, in my opinion, does not. I think if you’re in a division with Goff, Wilson and now Garoppolo off the injury, they feel that Kyler Murray – now that he’s in the range you need to be, close to Russell Wilson height-wise – I think he’s in line maybe to be the No. 1 pick overall now.

If the Cardinals part with Rosen after one season, what does that say about their organization?

They fired Steve Wilks after one season and might plan to do the same with Rosen?

Kiper mentioned that he doesn't think Rosen is a good fit for Kingsbury's offense. Is it because Murray has a stronger relationship with Kingsbury than Rosen does?

Murray is a dynamic quarterback who adds more dimensions to an offense than Rosen. However, Rosen has flashed some potential in 2018 and wasn't given a fair shot to prove himself with leaky pass protection in front of him and subpar talent around him.

Rosen is not as athletically gifted as Murray, but the Cardinals must show some commitment to either the coaching staff or their players. Rosen has talent and must be given a fair chance to succeed.

There are too many rumors surrounding Kyler Murray and the Cardinals. People are beginning to think it will actually become a reality… including Mel Kiper.

Cardinals GM Steve Keim might be trying to get teams interested in trading up for the No. 1 pick. Multiple first-round picks will certainly go a long way toward improving the worst team in the NFL.

It's possible that Kiper will be right and the Cardinals will take Murray. That will be settled on draft day, April 25.

Will the No. 1 pick be Kyler Murray or Nick Bosa? Kiper doesn't have the final say.
