Just further proves just how freakin bad Rex was. Let face it, going into the season this secondary was not highly thought of. You lost the biggest FA CB in the league, traded away a 2nder rb CB, signed Hyde to mid level contract and Poyer was a former 7th rd FA. So at corner you are starting a rookie and a 6th rd pick of the Rams-Gaines. Plus it seems that past teams have kept more DBs on the roster.
What McDermott and Frazier have done with this group is the definition of coaching up, and Rex was regression...the game has passed him by.
