Landry's stats over 4 years are pretty telling; they tell me that Miami throws the ball to him WAY too many times when they should be running more and throwing down the field for chunk yardage. Everyone keeps saying how he's so great, and that he's their best offensive player. I see Landry as an anchor weighing down the offense. They keep throwing short passes to him because one, Philbin and Gase both prefer a short pass based offense, and two, they can't/won't build a tough physical o-line so the QB is usually under pressure and has to dump off the ball to Landry (which is pretty much what Gase wants). In 2016, Tannehill started moving around more (both by design and due to pressure) and going deep with the ball. This helped to open up the running game for Ajayi, and the result was 10 wins and a playoff berth. What happened this year? Take away Tannehill and the deep threat and the offense went in the toilet. Landry still got his stats though, so logic tells me that Landry and his stats have nothing to do with winning games or making the playoffs.
I say let him leave. Get a seam-threat TE not named J. Thomas and give Carroo more playing time. Chances are no one will miss Landry.
