The need for a #2 is less about catching the balls that currently go to Kincaid, Shakir, Cook, etc., and more about having a dangerous enough weapon opposite Diggs to prevent defenses from focusing so heavily on him.
If a #2 receiver reduces the production of Kincaid and Shakir, I don’t care as long as it INCREASES the production of Diggs. I I’m not saying I need 1,700 yards from Diggs — I’m saying I need a set of weapons so stacked that somebody on the defense is seriously compromised.
