The Packers might be interested in drafting Georgia Tech DE Michael Johnson because ProFootballTalk says so:

According to a league source, the Green Bay Packers are high on Johnson.

Johnson is exactly the type of player I want them to draft. A college DE who might be best suited as an outside LB in the NFL, who can rush the passer, and is a gifted athlete. Unfortunately this bio uses "inconsistent" and "has potential" too much for him to be considered a top 10 pick. Only 1 out of these 4 mock drafts even have him in the 1st round. 

But that might make him a candidate for the Packers' high 2nd round pick. He probably won't fall that far, too many teams seem interested in him, but he's someone to keep an eye on.
