I think the merits of moving CM3 to ILB are obvious. I only wonder why they didn't try it earlier - but maybe they felt they had to wait until the bye week to allow him to prepare for it.
The difference in reaction speed to the plays in middle of the field was incredible. In the time it seems to take AJ Hawk to decide to start to move, CM3 was already accelerating into the ball carrier or receiver.
CM3 is probably one of the top 5 OLBs in football, but he's about three orders of magnitude better at ILB than anyone else the Packers can line up.
He's not going to cover effectively Darren Sproles out of the backfield, but Tramon or Shields would be challenged to doing that. How's this for a comparison.
Player 1: 6'4" 258 4.6 40 Yard dash at combine
Player 2: 6'3" 255 4.6 40 yard dash at combine.
Player 1 is a Hall of Fame MLB/ILB - Brian Urlacher
Player 2 is CM3
I see him as an Urlacher type. An incredible athlete with a knack for making big plays.
