One big positive through two weeks of Dolphins training camp. And personnel notes

A six-pack of Dolphins notes on a Monday:

▪ Here’s one of the encouraging developments through nine training camp sessions: None of the young cornerbacks who will be on the team is being consistently toasted or looks overmatched.

Rookie second-round pick Cam Smith, while still a work in progress, had made at least seven pass breakups.

Noah Igbinoghene had an interception in Saturday’s scrimmage and is becoming increasingly - dare we say? - reliable.

Kader Kohou looks even better after exceeding all reasonable expectations last season.

Signing Eli Apple, in the wake of Jalen Ramsey’s knee injury, was prudent, because Miami needs the depth and you can’t count exclusively on youth (beyond Xavien Howard) in a pass-happy league.

But the kids are showing promise, with Kohou again likely to have the biggest role. And Ramsey could be back on the field by November, in the most ambitious of timetables.

Dolphins cornerbacks coach Sam Madison said Smith is well prepared for Vic Fangio’s defense because “Cam has played a lot of different coverages throughout the course of his career. And he takes it very seriously. He wants to be good, and he wants to put his best foot forward every single play.

“It’s just been fun throwing him in different situations throughout the course of the camp, and he’s handled it very well. I mean, he’s a true defensive back because, when you’re talking about giving up a play or coming up with a play, he has a short memory span, and then he gets right back out there and gives it his all.”

Kohou, remarkably, played nine games last season with a broken hand and still had a sterling passer rating against (83.9) as an undrafted rookie.

“He’s done a very good job,” Madison said last Friday. “Everybody in the league really knows who he is now and we will see what the next step is for him. He’s always ready to go, so I can throw him in different situations and he’s a strong-minded player and he just goes out there and does his job and he does it very well.”

Kohou could play on the boundary in base defense and then shift to the slot in nickel packages, with Apple or Igbinoghene or perhaps Smith on the boundary during Ramsey’s absence.

Tyreek Hill said Kohou “is another guy to look out for this year for a breakout season. Undrafted guy and he’s a dawg. He’s small, but he’s very strong at the line of scrimmage, and he isn’t afraid to tackle.”

And Igbinoghene’s strong Saturday scrimmage (an interception and pass breakup) continued a solid camp.

“He’s always one of those guys that’s always going to be in shape,” Madison said. “He’s always going to be prepared. Now he just has to go out and take that next step of becoming who Noah wants to become.”

Mike McDaniel mentioned after the scrimmage that Igbinoghene has “continued to progress and make more plays.”

▪ The Dolphins signed cornerback Parry Nickerson and cut quarterback James Blackman. Nickerson, a 2018 sixth-round pick of the Jets, has played in 25 NFL games, with three starts. He spent most of last season on Minnesota’s practice squad.

▪ Fangio might be the most unfiltered Dolphins assistant coach since Vance Joseph was Miami’s defensive coordinator in 2016. He never sugercoats and identifies where he believes his unit is not good enough.

After linebacker David Long made several flash plays over three practices, another reporter asked Fangio about Long on Friday, expecting effusive praise.

Instead, Fangio said: “He’s had ups and downs. He’s made some really good plays, and then some other plays that we need to get him honed-in on better. And he’s working hard to do that. But you can’t just have flash plays. You’ve got to have good plays all the time.”

▪ The good news is that Long and Jerome Baker seem to complement each other at inside linebacker.

“They play really well off of each other,” linebackers coach Anthony Campanile said. “They’re both good communicators. So, that’s been fun to watch. Their relationship is certainly very good, very strong.

“And in terms of physically, they have some similarities in their skill set because they’re both physical, both strong guys and both can really, really run well. So, we’re blessed and fortunate that way we’ve got two guys that can do that… [Long] had a lot of success in Tennessee. I’m excited about how he’s playing.”

▪ It will be interesting to see if Andrew Van Ginkel does enough to earn inside linebacker snaps once the regular season starts, in addition to an off-the-bench workload at outside linebacker.

“Andrew has done a great job for us since we moved him to inside part time,” Fangio said. “He’s still outside also. He’s picked it up really well. His football instincts and acumen flourish in there.

“He’s done a really good job for a guy – that’s a hard transition for a guy to move from an on-the-ball position to an off-the-ball position – and he’s done very well with it. It’s going to give us some good versatility throughout this season.”

▪ Emmanuel Ogbah’s role is evolving. Mostly a defensive end in the past, he’s playing more standing up.

“Ogbah, we’re moving him back and forth between the outside and inside,” Fangio said. “In nickel, he could be a guy that could rush from the outside. And in base defense, we’re trying him inside just because we still haven’t found a fourth, fifth or sixth d-lineman.”
