This feels more like coaching and scheme vs anything to do with Kincaid. For whatever reason his role has been sort of a dump off safety valve for Allen. His hands have been very good, and his separation has looked good as well. He passes the eye test for me to potentially be a top-5 receiving TE in the league (not sure about his blocking, maybe that is what has limited his involvement in the offense).
IMO he should have 10 targets per game, but that is just me.
