The Dolphins made a pair of injured reserve transactions today, according to the team’s official Twitter account, activating former starting left guard Liam Eichenberg while placing running back Myles Gaskin on IR. A year ago, both of these transactions would have appeared to be major, but at this point in the season, the moves may only affect Miami’s depth heading into a possible postseason run. 
Despite being selected early in the second round of the 2021 draft, Eichenberg has not seen the success of his early-round teammates drafted before him, starters wide receiver Jaylen Waddle, outside linebacker Jaelan Phillips, and safety Jevon Holland. Eichenberg became an immediate starter as a second-round rookie last season, starting 16 of 17 games at left tackle for Miami. The adjustment from Notre Dame to the NFL proved difficult for Eichenberg, who would grade out as the fourth-worst tackle in the league that year, according to Pro Football Focus (subscription required).
Miami tried to help Eichenberg out during his sophomore season, signing veteran Saints tackle Terron Armstead to a five-year deal and moving Eichenberg inside to left guard. While Eichenberg is no longer ranked at the very bottom of his position group (currently graded out as the 73rd-best guard out of 83), his PFF offensive grade has gotten worse since moving inside to guard. Eichenberg’s struggles came to a point when a knee injury in a Week 8 win over the Lions would land him on IR. Eichenberg’s knee injury was initially feared to be a season-ending MCL sprain, but further testing showed the potential for his return and, after proving fully healed, Eichenberg was designated for return on December 7, making tomorrow the last possible day for Miami to activate him before forcing him to sit out for the remainder of the season on IR.
In Eichenberg’s absence, the Dolphins started a second-year undrafted guard out of Middle Tennessee State, Robert Jones. Eichenberg’s return does not necessarily indicate a return to his starting role. The Dolphins may choose to go that route, but Jones has performed well in his seven starts in place of Eichenberg, even outperforming Eichenberg in the eyes of PFF. Jones currently grades out as the 39th-best guard in the NFL this season with grades far above Eichenberg’s. Head coach Mike McDaniel may choose to give Eichenberg a chance to earn his job back, or he may stick with what’s been working and count on Eichenberg as a depth piece as they push for a wild card spot in the playoffs.
Gaskin has taken quite a fall from grace after performing as Miami’s top running back for the past two seasons before 2022. It was assumed that Gaskin’s role would diminish when the team acquired running back Raheem Mostert in free agency back in March. What wasn’t expected was that college and professional teammate Salvon Ahmed would move ahead of Gaskin on the depth chart, playing in six more games than Gaskin. When Jeff Wilson was traded to Miami back in November, Gaskin became a depth piece in the running backs room.
It’s unclear exactly the reason that Gaskin is being placed on IR. Some reports claimed he missed last weekend’s game because of a knee injury, despite not appearing on the injury report, while other sources reported it was due to illness. Regardless, Gaskin will miss the remainder of the regular season, and since his team has five activations remaining, if his team can make it to the AFC championship, he will be eligible to return. Otherwise, Gaskin’s 2022 season has come to an end.
