The reason Fred Thomas was covering (or NOT covering) CJ all day is because Thomas normally plays the RCB position while McKenzie is our LCB. The Bengals lined up CJ at left flanker pretty much all day, meaning he would be covered by Thomas. To me, after the first time Thomas got burnt, Gibbs should've adjusted and locked up McKenzie on CJ the rest of the game no matter where he lined up. Unfortunately, that adjustment wasn't made and Thomas gave up two more.
