Yes.
They are not the same kind of receiver. Definitely don't think we would have drafted Jennings. Ursua may still have been in play as he's more a pure slot guy who could still alleviate the need to play Lockett in the slot.
Dorsett probably even now competes with Turner and Ursua for snaps. Before Metcalf, we had Moore for that role. So I do think the talent/role fit still stands regardless of if Dorsett is signed last year.
Big WR group: Metcalf, Moore (Lockett)
Speed group: Metcalf, Dorsett, Lockett
Slot/3rd down conversion group: Metcalf, Ursua, Lockett
Not to say Ursua is a lock. But it also seems like they've tailored their TE group to kind of mirror these roles. Seems a lot of crossover ability to incorporate 12 personnel to effect similar strengths.
