USC football continued preparations at Howard Jones Field on Wednesday, as the Trojans travel to Seattle to face the undefeated Huskies on Saturday, still with an outside chance at topping the Pac-12 South if they manage to pull off the upset.And the Trojans’ determination to do so was evident throughout practice this week. Recordings of barking dogs, screaming crowds and the Washington marching band provided the best imitation of Husky Stadium. USC has pulled out all the stops in an effort to gain an edge against Washington, but players credited a daily routine as the one that has helped the team progress throughout the season.“Iron Sharpens Iron”Every practice, the first-team offense and defense go head-to-head, and those in attendance get a chance to see matchups such as junior wideout JuJu Smith-Schuster taking on junior cornerback Adoree’ Jackson. The team calls it “iron sharpens iron.”“You get a real look at real starters in the Pac-12 — nothing can substitute for that,” junior safety Chris Hawkins said. “Going against [redshirt freshman quarterback] Sam [Darnold] and JuJu really helps us.”As a team that believes in its own talent, the Trojans think no one will push them harder than their teammates.“We’re always challenging each other in practice,” senior linebacker Michael Hutchings said. “And it’s paying off.”Housebreaking the HuskiesWednesday’s practice also focused on an efficient, pro-style Washington offense that has averaged 48.3 points per game: second best in the FBS. Head coach Clay Helton called the Huskies “the most balanced team we’ve played.”“They just line up and play good, sound football,” he said. “That’s the mark of a Chris Petersen team.”Indeed, Washington has threats scattered all over the field, from running back Myles Gaskin to the big-play receiving threats of John Ross and Dante Pettis. But most eyes will likely be focused on the Huskies’ quarterback: Heisman candidate John Browning.“He’s really a general for their offense. He gets everybody going,” Hawkins said. “He doesn’t really make mistakes … and he gets the ball to his receivers.”Facing a tough task this weekend, Hawkins called for the squad to rally around Helton.“I will say this. This is his biggest game,” Hawkins said of his coach. “We’ve got to go play for him and for ourselves. We want to bring USC back to where it used to be, and this is a big step in that way.”“We can’t worry about anyone else,” Hawkins summed up. “The season is on the line every week.”Injury UpdateHelton also provided updates on injured Trojans. Defensive tackle Stevie Tu’ikolovatu made progress coming off a platelet rich plasma injection in his knee, and Helton said he “wouldn’t be surprised” if the redshirt senior played on Saturday.
