Likely signing pushes Johnson to blocking role; Nagy system may create some targets.

Giants tight end who played well last year with some splash plays but also made mistakes; is a strong blocker and was expected to be the team's primary tight end option. However, Harbaugh's signing of Isaiah Likely to a significant contract signals a shift in the tight end hierarchy. The source ranks Likely well ahead of Johnson, suggesting Johnson will assume more of a blocking role while Likely handles the receiving duties, though Nagy's historical preference for a lead tight end could create some target opportunity for Johnson.
