I'm not saying Jordan will be as good as these players but to answer your question of successful pass rushers who started off as poorly as Dion.
These are the players that finished their careers with 100 or more sacks in their careers who started their careers with two or fewer sacks.
Kevin Greene 160 career sacks had 0.0 sacks as a rookie.
Chris Doleman 150.5 career sacks has 0.5 sacks as a rookie.
Michael Strahan 141.5 career sacks had 1.0 sacks as a rookie.
John Randle 137.5 career sacks had 1.0 sacks as a rookie.
