David Njoku, Cleveland Browns
This one is tough to gauge as the resurgence of David Njoku in the world of fantasy football is directly tied to the return to the league of Joe Flacco, who is absolutely balling out.
But we can hope that it sticks with Njoku, who was highly-touted coming out of college. Yet, he had never had more than 58 receptions in a season and was certainly part of that "tight end scrap heap" that most fantasy managers were choosing from back in August.
But this season, he has caught 81 passes. Only three tight ends (Kelce, Hockenson, Evan Engram), have caught more. But he also has 882 receiving yards and six touchdowns. Watching him in recent games where he catches a pass from Flacco and has room to run, he is a problem for any defense to contain.
He's still just 27 years old so there should be plenty of tread left on the tires. When you consider the terrible accident he suffered earlier in the season, his play this season is even more remarkable.
