A year ago, we had a good time talking to people about new GM hires such as Mike Borgonzi (Titans), John Spytek (Raiders) and Darren Mougey (Jets). The newest GM of this cycle is Jon-Eric Sullivan, who’s taking over in Miami as the successor to Chris Grier.

Jon-Eric is an interesting guy. He’s got a strong pedigree as the son of an NFL lifer (longtime receivers coach Jerry Sullivan), as well as a very strong, very stable foundation in player evaluation after rising through the Packers front office over two decades. He’s also been honored by his peers twice (2022, 2025) as a winner of a BART List Award for scouting excellence. However, I’ve never worked with him, so I reached out to several people who have. Here’s what they told me — off the record so they could be completely candid.

  • “First of all, he’s a football junkie. . . with his dad being . . . arguably one of the best receivers coaches in the history of NFL, you know, and the things that he learned from being around him, he just simply knows football. He is a grinder. He works his ass off . . . not only from a football standpoint, but he takes care of himself (as a) healthy, fitness-oriented type of person. . . He’s a great family guy with a beautiful family . . . fun to be around. Good energy to be around.”
  • “Incredible eye for talent, sees the big picture. Outstanding at fostering and maintaining relationships. Most importantly he LOVES football and is passionate. Does a great job listening while still having his own convictions!”
  • “He is a true football guy through and through . . . from coach’s son, to player, to scout. The guy knows players and he knows ball. If given the time and proper supporting staff he will be one of the best GMs in the NFL no question! Honestly, this is long overdue!”
  • “Love Jon-Eric Sullivan. Great guy. Smart. Good evaluator. Raised the right way in this business.”
  • “Obviously, great human being and evaluator, but he’s well-equipped on the salary cap side as well. Green Bay does a good job training their guys in that regard. Not an indictment or anything negative about Miami’s roster, but there was an emphasis on building the culture in addition to the talent pool in Green Bay, and I’m sure he will take that with him. I’m excited to see how he builds the roster and who he hires as head coach.”
  • “Good man who knows how to lead. How he makes up his staff will tell you more than you think.”
