Yesterday our very own Sam Householder speculated on a few Chicago Bears' veterans that could end up as surprise cuts. He specifically hit on the linebacker position, because that seems to be the most jumbled with so many guys learning new positions.
There are 4-3 outside linebackers converting to 3-4 inside linebackers, 4-3 defensive ends converting to 3-4 outside linebackers and a 4-3 Mike backer learning to play inside in tandem with a Jack inside linebacker. There are only two veterans at the position that have ever played in a 3-4, Sam Acho and Pernell McPhee.
