One of the strength of Ted Thompson was that he kept WR depth full, so that while there might not of been a great #1, the #3 WR could usually consistently beat the #3 CB.
I think that's why MM's isolation scheme fell apart, is that the Packers lost the WR depth with basically just Adams.
Depth is more important than one, or two single stars. Especially when injuries start becoming a factor.
Packers need to secure depth elsewhere, OL, RB, S, CB, and need another stud run stopping DT.
