If you follow the dots or draft info about Miami's draft interest, you'll see a pattern.
They've only met with 2nd and 3rd tier offensive lineman, up to this point. Haven't been interviewing the top tier OT's and outside of JPJ, haven't shown any interest in any of the expected 1st rounders.
Miami has shown interest in lots of the DT prospects. There are reports of interest in the Dline prospects from, Baylor, LSU and Alabama as well as Newton from Illinois. Miami's Dline and Asst Dline coach have coached players from these schools. And Weaver appears to have a connection to Latu, the edge player from UCLA.
Miami has shown interest in a few TE's. More specifically in Erick All. Who's been to Team Headquarters.
Grier has shown interest in several of the DB's in this draft class. Cooper DeJean in particular. Also Elijah Jones from Boston College, whom Miami has a connection to.
Although they've been linked to WR's in F/A, it doesn't appear they've been linked to anyone other Worthy, whom coach McDaniel, shook hands with at pro day.
This might not mean anything, but than it could. All the fan and online speculation about various Oline, WR's and TE's hasn't been verified. Everything I've posted about above has been verified by either a Dolphins beat reporter or team insider.
To me it appears Miami has something other than an OLineman in round one, on its radar.
