Still just 22 years old, Njoku owns the ideal combination of size at 6-foot-4, 246 pounds, and athleticism to become a dominant tight end force, if he can become consistent in all facets. Last season, he showed flashes of being a potential difference-making target for Mayfield, who can take advantage of mismatches over the middle, flying past linebackers and bullying safeties. His 639 yards and four TDs on 56 receptions showed promise, but the ceiling could be much higher.
