Eight quick hits from Dolphins general manager Jon Eric-Sullivan’s Monday session in Phoenix with a few South Florida reporters, including The Miami Herald’s Omar Kelly:

▪ The Dolphins know they need cornerback help, and while Sullivan likes the upside of the players at that position, he said nobody “has earned anything” yet in that room.

“That whole back end is competing for their jobs,” Sullivan said. “I like who’s on the roster. Those guys would all tell you no one has established themselves for whatever reason, whether it’s injury or inconsistent play. We are going to put them in a bag and shake them up and see who… wins the job. I’m going to do everything in my power if there’s one available that’s a stud, I’m going to go get them.”

Though Sullivan didn’t mention any draft players by name, Miami has been linked to LSU cornerback Mansoor Delane in mock drafts; he’s projected for the 9 to 14 range. He’s among the prospects who has been invited to Dolphins headquarters for a visit.

“Nobody has earned anything yet,” Sullivan said of the cornerback room. “Nobody has established themselves yet back there. That’s just the truth of the matter.”

▪ Sullivan endorsed left tackle Patrick Paul and center Aaron Brewer but said “there’s going to be competition” elsewhere on the line.

“[Left guard Jonah] Savaiinaea will be first one to tell you he has got to be more consistent,” Sullivan said. “On the right side, we have some questions we need to get answered. [Right tackle] Austin Jackson. We’re excited to get him back; he needs to stay healthy.

“We are going to have competition at the right guard spot. I like a lot of pieces on our offensive line — our left tackle and center especially. There’s going to be competition elsewhere.”

▪ Sullivan said he’s “very happy with our defensive line. I like our young defensive tackle room. Jordan Phillips [Kenneth] Grant, [Zeek] Biggers. I like Zach [Sieler] obviously; he’s a good, established player. I like our defensive line. We will continue to add to that.”

▪ Sullivan said the draft is particularly strong at three positions:

“There’s depth at the edge spot. [There’s] a lot of safety depth. Inside linebacker, there’s depth and substance there. Those three positions, this draft relative to most, if you don’t get a guy in the first round, you have a chance to get a chance in the second, third round.”

He also said “it’s a really good wide receiver draft. [There are] some very good players up top; there’s depth and substance to it in the second, third, fourth rounds.”

▪ He said the team’s receivers — including newcomer Jalen Tolbert — “have something to prove and understand they have something to prove. They understand what the narrative is with [them, that] nobody is expecting much. They’re chasing the carrot. “It’s my job to put more substance in that room. We have to surround Malik [Willis] with good football players. We’ve got to put playmakers around him.”

▪ Might Sullivan trade down from picks 11 or 43?

“You never know how it’s going to unfold. It truly depends on how the board falls and what’s available. I’m all for acquiring picks, but I’m not getting an award for [volume of] draft picks…. I will never pass on a very good player to acquire picks unless there are very good players I know I’m going to be able to get.”

▪ Speaking of the team’s new edge players, Sullivan said Joshua Uche “will play a lot of SAM [linebacker] for us at times… You can let him go rush. He’s wired right. Tough, physical. [David] Ojabo is excited. He’s a bigger body. He’s got length, got a physical presence. He’s a little bit of a different body type than we have, which I think we need. We will keep adding to the room, throw them all in the mix and see what comes out.”

▪ Speaking of returning edge player Chop Robinson, Sullivan said: “He has a responsibility, has to be intentional about his business… I have a lot of confidence in [coach Jeff Hafley] his staff and their ability to teach and develop young players.

“Chop has a lot of natural talent. We have a lot of really good coaches in the building. I think it will be a good marriage. We will get the most out of Chop.”
