Tight end is one of the hardest positions in the NFL to transition to as a rookie. You rarely see a rookie season breakout as a tight end, as the jump usually takes at least one year. The Chicago Bears are prepared for this, as they have Jimmy Graham and even Demetrius Harris as depth to ease in their second-round draft pick Cole Kmet.
Still, they are going to want to get Kmet on the field as a complementary piece as a rookie and want to run more two and three tight end sets overall.
