At some point, the complexity of the Dolphins offense Josh Rosen is learning should work to his advantage. But for now, it’s a challenge.

“A steep learning curve,” Rosen said after an organized team activity practice on Wednesday, his eighth with Miami.

Rosen had three different offensive coordinators in three years at UCLA. And he had two offensive coordinators in his only season in the NFL, at Arizona.

So Rosen has seen a lot. And that should help — eventually.

“It’s actually kind of similar to Coach (Mike) McCoy’s in Arizona because he was with – it’s a long tree – but I think he was with (Josh) McDaniels in Denver and that tree kind of flows here,” Rosen said of all his route options. “There are a lot of differences but some things are a little bit the same.”
