​The 2026 Miami Dolphins are closing in on the start of their training camp, with just days remaining before the rookies start reporting. The 90-in-90 series (which, admittedly, has seen a few breaks in what is supposed to be a daily series) continues today with a look at a veteran who will be battling with several rookies this summer.The team’s top linebackers are still Jordyn Brooks and Tyrel Dodson, but the team added rookies Jacob Rodriguez (2nd round) and Kyle Louis (4th round) in the 2026 Draft to bolster the position group. Ronnie Harrison, Jr., also joins the position group this year, signing a one-year contract to provide veteran depth to the position – even if he has to battle through the rookies to find playing time.AdvertisementAdvertisementAdvertisementName: Ronnie Harrison, Jr.Number: 56Position: LinebackerHeight / Weight: 6’2” / 207 poundsAge (at start of season): 29Experience: 9th seasonCollege: AlabamaDraft: 2018 3rd round (93rd overall) – Jacksonville JaguarsAcquired: 2026 free agent signingContract: 1-year, $1.4 million2026 salary cap: $1.2 millionContract details via OverTheCap.com.

He only played about 40 percent of the defensive snaps for the team during the season, working as a rotational player, but he did appear in 67 percent of the special teams snaps.AdvertisementAdvertisementAdvertisementTre’Shon Diaz at SB Nation’s Falcons team site, The Falcoholic, reviewed Harrison’s 2025 campaign, writing:The late camp addition proved to be a well-timed signing. Harrison would end up supplanting Bertrand as the third linebacker in rotation, and it was because he could handle the speed of the game. He also provided some juice in pressure packages, racking up seven pressures and two sacks. For the cost of his services (1.2 M), Harrison was a bargain.However, there were still faults with his game. Harrison had the highest missed tackle rate (20.6%) in the Falcons linebacker room. His slimmer stature also showed up in the run game, where he struggled taking on linemen. It’s unlikely he’s poised for a larger role in the future, but he’s proved that he can be a serviceable option in relief and has earned a shot at coming back in 2026.Inside linebacker signings: Willie Gay, Jr. (re-signed), Ronnie HarrisonReleased: Jordan Colbert (failed physical), K.C.

He is a special teams player who can rotate into the defensive lineup when needed, but he is not likely to be a major member of the rotation.
