4. Tony Jefferson is staying put (for now)
The Big 12 Defensive Freshman of the Year is a hard hitter with improving cover skills. Jefferson played so well last season coaches experimented moving the San Diego-area product to free safety early in two-a-days.
When Lewis went down with the toe injury, Jefferson moved back to “Roy backer,” the position he played last year, a hybrid linebacker/safety spot named after former star Roy Williams. Joseph Ibiloye, Jefferson's backup, turned some heads during two-a-days, so there's a chance Jefferson might move to free safety when Lewis returns.
5. Wide receiver is the team's biggest strength
Quarterback Landry Jones connected 131 times with All-American Ryan Broyles last season. But if defenses choose to double-team Broyles — which is difficult against a slot receiver — Jones has other weapons he can exploit man-to-man coverage.
Kenny Stills set freshman records last year. A big-play threat, Stills produced three touchdown catches of 49 yards or longer. Senior Dejuan Miller is fully recovered from a knee injury. Trey Franks steadily elevated his game throughout his freshman season. Jaz Reynolds is back in good graces following a year he redshirted.
