Dolphins continue adding to roster – The Splash Zone 3/15/25

Welcome to the Splash Zone, the quickest way to get your day started off right. We bring you a rundown of Miami Dolphins news from the last 24 hours.

Over the past couple of days, the Miami Dolphins have continued to add players to their roster in the hopes they can get back to the postseason. The Dolphins brought in K.J. Britt to bolster their linebacker room and he should be a nice depth piece for the defense and special teams. The Dolphins running back room also needed a physical presence, so the team added Alexander Mattison who should be used in short yardage situations while De’Von Achane and Jaylen Wright handle the bulk of the work. This last move will make all the fans sad as the team brought back Liam Eichenberg on the offensive line. As an emergency depth piece that is fine, but if he is in the starting lineup week 1, this is an utter failure.

You can check out that story here, and the rest of the day’s round-up below.
