Two aspects you’re missing with how Coleman fits into everybody eats and separation are
1. Everybody eats includes the running backs, WR screens, and relies on YAC. Having WRs that can effectively block downfield adds to that.
2. Larger WRs that can high-point the ball is a form of separation, especially in the red zone where speed is mitigated.
It’s certainly debatable if those particular skill fits were worth a trade down and high 2nd round pick when you could get that from a Mack Hollins. That said, neither Kincaid nor any of the other WRs on this roster were proven commodities with those traits.
That aside, I wasn’t particularly fond of Worthy or Coleman pre draft.
