BYU didn't have nearly the level of impact injuries that Utah had.
Hall didn't miss a single game last year and your best RB played
the entire year. Collie had nagging injuries but he played. Utah
lost our best offensive lineman, which happened to be the most
critical position on the oline. So Utah lost our top RB, top WR,
and top olineman. All of these players missed almost the entire
season. BJ missed several games. BYU doesn't even compare to Utah
in injuries last year.
