PULLMAN – Three Washington State players made their first career starts on Saturday and two more made their collegiate debuts. Of those five players, four were on the defensive side against a team ranked No. 4 in total offense heading into the weekend. The Cougars have been young on defense all season, typically starting three freshmen and a sophomore in the secondary. But against Arizona the Cougars’ youth movement was taken to another level. Redshirt freshman linebacker Peyton Pelluer started at ‘Mike’ LB for the Cougars, with true freshman Pat Porter starting at cornerback in place of Charleston White, who was injured two weeks ago against Stanford. Defensive backs Willie Roach and Kevin Griffin also made their collegiate debuts. The inexperience likely contributed to the success of Arizona quarterback Anu Solomon, who completed 26 of 38 passes for 294 yards and five touchdowns.
