Utah already faced a tough task against No. 22 Arizona State without starting quarterback Jordan Wynn, but if you lose the turnover battle 5-0 you probably wouldn't win with Andrew Luck at quarterback.
The Sun Devils dominated the second half against the sloppy Utes and turned a close game into a 35-14 blowout.
Arizona State improves to 5-1 and, most important, 3-0 in the Pac-12. The Sun Devils are in control in the South Division. The Utes, widely considered the Sun Devils top competition in the South, fall to 2-3 overall and, most important, 0-3 in the conference.
Wynn's replacement, Jon Hays, completed 18 of 30 passes for 199 yards with a touchdown and three interceptions. The Utes also fumbled twice.
Utah, in fact, saw three second-half drives end with turnovers.
Meanwhile, the Sun Devils, who have been known to be sloppy in the past, protected the football and got a push with penalties.
While it wasn't always pretty, quarterback Brock Osweiler had a strong game, completing 25 of 41 passes for 325 yards with three touchdowns and no interceptions. He also rushed for 34 yards on seven carries.
