We have soo many holes I personally think that weapons (as in more than one) are not a huge priority, even if they would be great. We do want another good receiver, especially with AT possibly retiring, and a 2nd RB as immediate needs... I also think Coker, XL and JTS all take steps forward next year so that is part of why I'm less concerned.
Coker was an absolute monster when targeted. He finished the season #10 at yards per target in the NFL - ahead of McConkey and Collins (tho eachs usage means that this isn't a fair direct comparison). His y/r was also good for 17th overall in the NFL. But if he can get his routes crisper, I think the sky is his limit.
