The Dolphins are entering a complete rebuild in 2019, with a new head coach, new front office head, and likely a new quarterback. New GM Chris Grier is continuing to make moves, as he’s bringing in Bills national scout Marvin Allen to be his new assistant GM, according to Adam Schefter of ESPN.com (Twitter link). It’s the latest in a series of coaching and front office swaps teams have made in the AFC East, with Adam Gase going from the Dolphins to the Jets, Brian Flores going from the Patriots to the Dolphins etc.

Schefter writes that Grier and Allen “have a strong relationship.” The Dolphins have perhaps the most unclear path forward of any team in the NFL with a ton of uncertainty, so Grier and Allen will have their work cut out for them. Armando Salguero of The Miami Herald chimed in with a tweet to say that Allen was “widely respected” and a “very good evaluator.”

Here’s more from around the league:

• We heard earlier today that Eagles right guard Brandon Brooks suffered a “serious” lower leg injury in the team’s loss to the Saints, and now we have some clarity. Brooks, who was recently named to his second consecutive Pro Bowl, tore his Achilles during the game, according to Zach Berman of the Philadelphia Inquirer (Twitter link). He wasn’t the only significant player to tear his Achilles during the game, as Saints defensive tackle Sheldon Rankins suffered the same injury. Brooks still has a couple years left back on the huge deal he signed in 2016, but he could miss a significant portion of the 2019 season with this injury. Pro Football Focus gave Brooks the ninth highest grade of any guard in the league, so it’s a massive blow to Philly’s offensive line.
• Speaking of the Eagles, Brooks isn’t the only member of the offensive line they might be losing for 2019. All-Pro center Jason Kelce hasn’t decided whether or not he is going to play next year, according to Jeff McLane of the Philadelphia Inquirer (Twitter link). Kelce told reporters he has considered retiring each of the past couple seasons, so it sounds like a real possibility that he calls it quits this offseason. The 2011 sixth round pick turned 31 in November. If he does indeed retire, the Eagles’ offensive line would be a lot worse off next year.
• Speaking of retirement, Antonio Gates isn’t ready to hang them up quite yet. Gates told reporters after the Chargers’ loss to the Patriots that he wanted to keep playing if the Chargers would take him back, per Josh Alper of ProFootballTalk.com. The all time leader in touchdown catches for tight ends was only brought back after Hunter Henry tore his ACL last May, so it’s unclear if the Chargers actually have any interest in retaining him for another year. The 38-year-old caught 28 passes for 333 yards and two touchdowns this season. If he did play his final game today, he got a garbage time touchdown from Philip Rivers as a nice sendoff.
