According to Mike Wilkening of Pro Football Talk, plenty of teams are lining up to take Jackson's temperature:
He?s played all 16 games in the last three seasons, recording at least 118 tackles in all three campaigns. He has experience in 3-4 and 4-3 fronts. Moreover, he has experience adjusting to new schemes and coaches, given all the turnover he endured in Cleveland, where he played for four different head coaches. What?s more, Cleveland?s consistent organizational churn could help him in free agency, given all of the former Browns staffers working for other clubs. A team captain in Cleveland, Jackson should quickly fit into any defense and locker room he enters.Wilkening cites there's a downside to Jackson that may keep teams away. His age (30) and his size (6'0", 240lbs) could work against him.
