Opposing Scouting Reports:

Michigan State on Nico Iamaleava:

  • "We had to defend him (Chiles) all training camp, absolutely," Spartans DC Joe Rossi said (courtesy of Michigan State Spartans On SI). "You've got a long guy with a really good arm who can run (in reference to Iamaleava). That is very similar to Aidan. So we've defended him all training camp and all spring."
  • "He likes to scramble up the middle," Michigan State defensive tackle Alex VanSumeren said. "He can scramble outside. He's mobile. It's going to be a challenge for us to shut him down, but I think we can. I'm confident in us."

UCLA on Aidan Chiles:

  • "Aidan, great guy," Bruins defensive back Scooter Jackson said during Tuesday's media availability. "He's a local kid. That was actually my rival when I was at Warren High School. He went to Downey. Great guy, great quarterback... Great arm, can run, great guy."
  • "Well, I need to watch a little bit more film, but the film that I have watched, that's a challenge because you've got to keep him contained," Bruins defensive end Jacob Busic said. "You saw it on the flip side with Nico [Iamaleava], nothing's more disheartening than when it's 3rd-and-15 and the quarterback takes off for 50 yards. You're like, 'Oh my gosh!'
  • "We're going to have that challenge with Michigan State. He's an athlete, he can run, so we've got to keep him contained. We've got to rush, we've got to get him off his points. But when we do get him off his points, we got to make sure that he doesn't sneak out."
