I agree the defense needs depth of talent. We are starting players I think are better suited to be rotation guys. Another factor is youth/inexperience. We are playing Vrable and McGraw because our depth is very green. We started two rookie safeties, an UDFA 2nd year ILB and the first guys off the bench were also rookie or 2nd year UDFA: Arenas, Studebaker, and Gilberry.
