As far as the ThatOne Jones signing.....good depth move. The Packards tried to make him a linebacker in their 3-4 scheme, but he was a liability in coverage. Not many 270 pound linebackers can hang with tight ends and tailbacks in coverage.
Zim Tzu will put him in the rotation at defensive end, and defensive tackle on 3rd and long.
Not sure if Packard fans will have a jersey burning like when Brent Favre decided to wear The Horns.
