Joe Arrigo has list of names that the Packers are interested in. Of the mock drafts I've read, it seems likely that all the 1st round graded players will be gone by pick number 16 except WRs Ted Ginn and Robert Meachem, and CB Darrelle Revis. It seems unlikely that GM Ted Thompson would draft a CB in the 1st round when the Packers could use a RB, WR, or S, but it wouldn't be a surprise to see the Packers move down and select a CB in the 2nd or 3rd round.
He also discusses that the Packers are "seriously considering" trading up for either WR Calvin Johnson or RB Adrian Peterson. Thompson has never shown any intention of trading up. He rarely trades up in the later rounds.
There are a couple other rumors discussed too. Go to PackerChatters.com and read his whole article.
