TT and MM seem to be on the same page when it comes to drafting and I would think they have that list pretty well set by now.
I agree with your general premise that they have a chart of players who they think would be there at 16, but I don't think the list is well set at all.
You still have workouts for certain players left (notably Ted Ginn Jr), and you still have players who you can bring in for scheduled visits.
For example, if Ginn Jr runs a low 4.2, it is hard to say that his stock won't shoot up. So if the Packers think they have a shot at him right now, it might end up being different.
Also, I vividly remember TT saying after he drafted Rodgers that they became aware of Rodgers possibly falling to them in the week before the draft when the final mocks were coming out from different sources. That would suggest that until the Friday before the draft, TT will hav a general idea but no set list complied.
