I found a little "baggage" on Jackson, straight from his scouting report:
Character: Jackson is well-liked by his teammates and coaching staff, and was considered one of the team's prime locker room leaders. He commands respect on the field for his ability and is the type of player you never have to worry about getting into trouble. He is involved in community affairs and has been responsible and respectful. GRADE: 6.2

Oh, and Ayers was arrested for aggravated assault in 2005.
Jackson has more of an ideal build for 3-4 end too, he's projected to be more of a run stopper than a sack threat though, I think he's worth of our first round pick though, if we get a middle of the pack pick. He could be on the board well into the late teens too, get a couple more picks from that if possible.
