every years players come and go. With Kerry gone i completely trust Rex in shaping a defense to his likeing. Faneca lost a step last year and i remember the dolphins game where he got knocked over and sanchez got sacked in the red zone. Leon lost more then a step he lost a leg and we want young hard hitting RB's now that we have LT. TJ will be missed because of his durability but hes no longer a #1 RB and on a running team I feel we want more youth and versatility out of the position. So basically dont worry so much on every move.
