Naw, good teams reload because the backups compete against some of the best players in practice. Our Oline will have four returners alone I believe so not sure whwere you got 3. Also, we sub in a lot of players and with our talent should have a handful of games where we will get the backups meaningful snaps.
That depends on what you see as a returning starter. They are losing 3 starters in Foster, Newell, Schweiger. But they also return Downing, Remsburg, Simmons, Ramos, who have all started games. OL is by far our most experienced position heading into next year and that's with losing those 3 guys.
