IMO da Bears have to get a free agent WR, for the prior NFL experience, and a draft pick WR that can either play immediately, or be developed, but good enough to make the team. Would also add a WR or two to the practice squad.
Also have to draft a TE, or sign a free agent TE. Would think about adding a TE to the practice squad also, but there are only 4-6 practice slots, so might not be able to add both a WR and TE to practice squad, because need a QB on the practice squad, no doubt!
