You have the most under utilized receivers in the game already with garbage throwing the rock. Your focus must be solely on a qb that can make all the throws, else you'll have yet another target standing idly with their hands up while shaking their head.
Draft a 6th rounder sure, but find a qb. Outside of Gronk, Brady has thrown to mostly anonymous guys over his tenure. He's made Julian Edelman a star, which should illustrate that it isn't who is on the receiving end on the rock.
But, by all means, get another stallion who never sees the ball, Watkins and Woods need company.
