Matthew Stafford’s back responds well to one-hour workout, enabling him to practice with more confidence as Rams prepare for season opener.

Leavitt, a redshirt sophomore, showed plenty of promise in his first year as the Sun Devils' starter. The 20-year-old QB threw for 2,885 yards, 24 touchdowns and six interceptions, and he rushed for another 443 yards and five touchdowns.

Sean McVay says it’s “a step in the right direction” for the veteran quarterback, who missed the first four weeks of camp with an aggravated disc in his back.
