This is a hot take. I just don't think we have the necessary personnel to use him at his optimum position coupled with the fact that Haley was trying to use him as a deep threat half the time, which really isn't his game.
Jarvis is at his best when he is moved around the field, creating mismatches in the middle of the field. That is where a lot of his production came in Miami. He didn't start out as their #1 WR - he essentially became that because they had more weapons, which created mismatches for him, leading to a lot of volume. While he's received that usage here, more often than not he's lined up along the sideline facing the opposing team's best corner.
Landry has a unique skill set that shouldn't be overlooked - great hands, great YAC ability , and athletic as they come but we still need your prototype possession receiver - big guy with great hands and a reliable deep threat to create better opportunities for him.
