Hatcher was second fourth in "big plays" and second when based on playing time. Hostile's answer is correct. Spears was first on both counts -- 11 "big plays" and one every 40.4 snaps played.
Here are the numbers, using the defensive coaches' film stats for sacks, tackles for loss, forced fumbles and fumble recoveries (nobody had an interception) --
Spears 11 (one every 40.4 snaps played)
Canty 8.5 (one every 80.2)
Ratliff 8 (one every 88.9)
Hatcher 7 (one every 52.4)
Johnson 4 (one every 52.5)
Bowen 0
