It's hard to envision what the Packers will do when it comes to creating depth. At this point, we have no idea what they feel is necessary through FA, and what will be taken care of in the draft. I have a hunch the FA hunt won't begin until after the draft is complete, and they can assess what they actual get through that route. They'll probably gamble that at least a couple of their lower round draft picks will be serviceable as back ups, after they gain some camp and preseason experience.
It's all a guessing game until then.
What I am curious about is what they determine is the priorities in the draft. I think they'll mix it up, but their top couple of picks could be defensive front seven. After that, a couple of picks to augment the offensive line.
There are so many low level wide receivers in this draft that investing in the 6th and 7th round could actually find a diamond in the rough. Look towards someone who has size and speed, good route running technique, understands the reads on the field, and played for a school whose passing game sucked because of the coaching, offensive line, and/or the QB. They're out there, just gotta do the homework.
