The NFL supplemental draft will take place next Monday, though I don't expect the Green Bay Packers will get involved. But they did select former OL Mike Wahle back in the late 1990s when GM Ted Thompson was working in their front office, so it's possible they'll select a player and I'm sure they have done some scouting on these players.
QB Terrelle Pryor (Ohio State). I think we all know about him, and most everyone has a strong opinion of him. It doesn't seem likely that the Packers would draft him, but it's not impossible since he's certainly a talented athlete.
RB Caleb King (Georgia). He's got the size and speed that the Packers have been looking for in running backs, but I'd be surprised if they thought better of him then current undrafted free agent Brandon Saine, who came out of college with similar size and more speed.
DE Keenan Mace (Lindenwood). He's an interesting story because the Cowboys had signed the former indoor football league player to a contract as a 5 technique DE project, but it wasn't approved due to eligibility requirements and Mace is now required to go through the supplemental draft. I expect he'll go undrafted and the Cowboys will sign him as a free agent, as they intended to do a few weeks ago.
DE Mike McAdoo (North Carolina). He's another player from the school that got caught up in the whole mess with players receiving illegal benefits. While others like Robert Quinn decided to turn pro, according to NFL Draft Scout, McAdoo attempted to return to school, however, the NCAA would not rule him eligible. At 6-6 248 lbs., he's a linebacker candidate in the NFL who could possibly interest the Packers.
DB Torez Jones (Western Carolina). He's a small player who played at a small school, but he had 4 INTs in a college game, and he could draw some NFL interest for his ability to grab an INT.
DB Tracy Wilson (Northern Illinois). Reading between the lines on his bio at NFL Draft Scout, he might be better against the run as a strong safety than in pass coverage. If Aaron Rouse didn't sour the Packers on that type of player, I don't know what will. Plus, the Packers have better depth at safety than they've had in recent seasons, so I doubt they'll be interested.
